FinoMag Magnetic Planet
We welcome you to be our partner towards continuous success and expanding growth in manufacturing, design and enhancing the best magnet material and custom magnetic solutions. Contact FinoMag Magnetics today to learn more about magnet technology and magnet industry.
While we adore our magnets, handling and proper storage plays a vital role with safety. Below we included several tips and rules for proper handling and storage of our exclusive magnets.
- Keep magnets away from magnetic media (computer and/or TV
monitors, cell phones, credit cards, or your favorite motel room key) and
pacemakers. - Store these magnets in sealed containers. This prevents metal
debris cluttering your magnet. - If several magnets are stored in one container, place them in
attracting positions. - Alnico magnets: These magnets are made with aluminum, nickel,
cobalt, copper, iron, and sometimes titanium. These magnets are stored
with “keepers” or magnetic steel plates that connect the poles
of the magnet. Additionally, alnico magnets should remain sealed if not
used due to high sensitivity of demagnetization. - Due to their strength and unpredictability, neodymium magnets
can attract ferrous particles based from their surroundings. It’s best to
keep them in closed containers and stored away from magnetic media or
sensitive electronics. - Neodymium magnets are brittle; avoid collision to prevent
flying fractured chips. Use the provided spaces to protect the magnets,
reducing the force between them. - Avoid moisture with neodymium magnets. They’re prone to
moisture absorption, so store them in low moisture and humidity environment
to room temperature. - Space-magnets require sufficient storage space because of their
strength between other magnets and materials. Insufficient shelf clearance
can trigger sporadic shifting and/or jumping during access and removal.
Here at FinoMag Magnetics, we use secure packaging methods of neodymium magnetized alloys, one of the most strongest magnets created. Depending on the size and customer’s needs, our magnet packaging methods vary per order and magnet type.
Below, we have included general packaging and shipping information regarding our magnets. For additional questions and/or concerns, please contact your Bestec customer service for further assistance.
Quarter-sized or smaller magnets:
Due to the size of the magnet, they may or may not come with plastic spacers between them. This reduce the attracting force between the magnets, so upon shipment, your magnets will not stick together.
Additionally, these magnets are normally placed in attracting rows. These rows will arrive wrapped in corrosion inhibiting paper or VCI, and arranged attracting in a brick. The bricks are also packaged in carboard or wrapped in foam.
Magnets up to two squares:
Ordering magnets measuring up to two squares will come with spacers between each magnet. Additionally these pieces are arranged in attracting rows, containing lengthy spacers. Larger-sized magnets may arrive wrapped in foam.
Due to size of the magnets, smaller quantities goes in a labeled cardboard box. However, if the volumes are larger, then the magnets are crated.
Finally, large magnets, arrays, and/or assemblies are packaged in wooden crates. These would ship via LTL carrier.
Shipping
The Federal Aviation Administration (FAA) classifies packages which have an external flux density above a specified value as hazardous goods and most air carriers do not accept magnetized material; As such, the majority of our neodymium magnets are shipped by ground-borne couriers such as Fed Ex and UPS, and LTL (Less than TruckLoad) carriers for larger orders.
FinoMag Magnetics is able to ship products by air, but a handling & packing charge maybe applied for larger volumes to cover the additional shielding, labor and administrative costs that these require, though this will only apply in very exceptional orders.
We understand that people have questions regarding their magnets. As you know, there’s no such thing as a silly question (unless you ask one, wanting to get a silly answer). We’ve comprised your frequently asked questions in this friendly and highly informal section to aid you during the creation, purchasing, shipping and handling process!
- How do I order magnets?
- Before placing an order for your magnet(s), you will need to have an idea of what you would like and/or wanting to accomplish. Here are several items to consider before placing an order:
- General Nature of Application: Holding, transporting, lifting, etc.
- Desired Shape of Magnet: Ring, disc, semi-circle, rectangle, etc.
- Desired Size of Magnet: Diameter, length, width, and height.
- Tolerance and Conditions: Consider the allowed dimension variations, elevated temperature, humidity, and if it’s for primarily indoor or outdoor usage.
- Required Strength of Magnet: How many pounds of holding force or Gauss can it take?
- Magnetic Cost and Quantities: Determine average budget to help eliminate certain materials from consideration; also consider how the quantity needed for your said project.
- Will magnets lose their power over time?
- Generally, yes, magnets will lose their power over time. However, certain magnets will lose a small fraction of their magnetism. For example, Samarium Cobalt materials are shown to lose less than 1% of their magnetism within a decade.
- Permanent magnets do not lose their magnetism ever.
- How do you measure the strength of a magnet?
- The most common methods to measure the strength of the magnet is either the Pull-Testers, Magnetometers, or Gaussmeters. The Gaussmeters measures in Gauss, Magnetometers in Gauss or arbitrary units, and Pull-Testers measure pull in pounds, kilograms, or other force units.
- Are there special Gaussmeters to measure the strength of a magnet?
- Yes, however some can cost several thousand dollars. Bestec Magnetics use several types of Gaussmeters that range between $400 to $1,500+ each.
- What’s a magnetic assembly?
- Magnetic assembly is where the magnet is incorporated into a housing or permanently mounted to another part of it. This practice is common with unique types of magnetic assemblies, designed to increase the pull strength.
Additional Information
While we fill our minds with youthful and useful knowledge of magnets and advanced magnetism, in this portion we’ve included additional helpful benefits to make your magnetism more smooth and worthwhile.
- Most common types of magnetic assemblies are designed to increase the pull strength of your preferred magnet. Additionally, depending on the assemblies can pull more than 30 times its strength, like the round and channel bases.
- Magnetic assemblies offer a detailed variety of benefits, like mechanical and magnetic strength advancement, integration of mounting features, and protection against corrosion.
Density.
The density of a material specifies the mass of a given volume of the material; The density of an object is found by dividing it’s mass by it’s volume. Densities are typically given in units of “grams per cubic centimeter” i.e. “What is the mass of a cubic centimeter of this material?”.
A magnet’s density allows you to determine the mass you require from it’s volume, or the volume you require from it’s mass. The densities of several different magnet types are given in the list below:
- Neodymium : < 7.5 g cm-3
- AlNiCo: 6.9 to 7.3 g cm-3
- Samarium Cobalt : 8.2 to 8.3 g cm-3
- Ferrite: 5 g cm-3
- Flexible : 3.5g cm-3
Pole.
Magnetic field lines must originate at one point of a magnet and terminate at another in an unbroken line. By convention, the point of origin is known as the ‘north pole’ and the point of termination known as the ‘south pole’. Magnetic field strength is highest around the poles as this is the region with the greatest density of field lines or ‘flux density’. In the same fashion as positive and negative charges, regions of the same pole will repel each other and regions of a differing pole attract each other.
Direction of Magnetization.
The center point of a magnet’s north and south poles must lie along the same axis; However, at Bestec Magnetics, we have complete control of the our manufacturing process from synthesis from raw materials to packaging and shipping, this allows us to determine the orientation of this axis. Enabling us to produce products with a wide variety of potential applications. For example, the poles in our anisotropic rectangular magnetic can be oriented in three directions, and this must be specified before manufacture. We are also able to fine-tune a number of other characteristics of your magnet or magnetic material to fit almost any potential purpose.
Magnetic Flux Density: Gauss, Tesla & Magnetic Remanence.
Magnetic fields can be imagined as a series of field lines (or ‘flux’) originating from a magnet’s north pole and terminating at it’s south pole; the force experienced by a magnetic object in the field is directly proportional to the flux density of the region it is positioned in. It is important to remember that flux density does not represent a magnet’s total pulling or pushing force since it is a measure of density; a large magnet with the same flux density at it’s surface as a small magnet has greater potential attractive force. Magnetic flux density is estimated by differing units with differing applications which should not be confused when selecting a magnet:
Remanence is a property of a magnetic material determined in the manufacture process, it estimates the magnetic field strength inside the magnet that remains when the magnetization process is complete; it represents the grade of the magnetic material rather than the pulling or pushing ability of the external field. It’s equivalent guass value will be much higher than that of the external field and should not be taken to be indicative of it.
Gauss directly describes field line density and so the force experienced by an object in the field external to the magnet, the unit Gauss (G), is defined by the current generated by a loop of a perfect conductor passing through the field. The Earth’s magnetic field at the surface is approximately 1 Gauss on average.
Since one Gauss is, for our purposes, an extremely small unit, there exists a larger one known as a Tesla (T) equal to 10,000 G and is defined in much the same fashion
