Magnet Grades - K&J Magnetics

Grade N42 magnets have a Br of 13,200 Gauss, while N52 magnets can be as high as 14,800 Gauss. See our Specs page for more Br values for various neodymium magnet grades. The Surface Field is the strength of the magnetic field measured right at the surface of the magnet. It's the field strength you might measure if.

Neodymium magnet - Wikipedia

A neodymium magnet the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest.

Why Magnets Lose Strength | Dura Magnetics

An example of a static case of demagnetizing fields from neighboring permanent magnets could be a Halbach Array where some internal magnets have a poor L/D and low Hci and are demagnetized from other array magnets. A dynamic case could be a permanent magnetic toque coupler which “slips” and like magnet.

Permanent Magnets

The table below contains some data about materials used as permanent magnets. Both the coercivity and remanence are quoted in Tesla, the basic unit for magnetic field B. The hysteresis loop above is plotted in the form of magnetization M as a function of driving magnetic field strength H. This practice is commonly.

4 Factors Causing Your Magnets to Get Weaker - Jobmaster Magnets

Temperature variation can cause magnets to lose some or all of their magnetic charge. Depending on how extreme the temperature, these losses can be temporary or permanent. Magnets exposed to temperatures not outside their reversible operating temperatures may temporarily lose strength while heated, but will regain.

Frequently Asked Questions - Amazing Magnets

Neodymium magnets are the strongest rare earth magnets and the strongest magnets in the world. 2. What does the N35, N40, N42, N45, N48, N50, N52 grade mean? Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the.

What Causes a Permanent Magnet to Lose Its Magnetism? | Sciencing

Apr 24, 2017 . . will realign in the same direction, strengthening the magnet. Without a strong magnetic field to guide the atoms, they will realign in random directions, weakening the magnet. Most permanent magnets can hold up to being dropped a few times, but it will lose strength from repeated strikes with a hammer.

What affects the strength of a magnet? - Cool Magnet Man

Material. As seen in the previous section, and copied below, the material the permanent magnet is made from has a significant effect on the overall strength of a magnet. The material will also determine how its flux is affected by temperature, and how easily the magnet can be demagnetized by opposing magnetic fields.

Strong Neodymium Magnets | Discs | Blocks | Rods | Rings

Neodymium (Neo or NdFeb) magnets are strong permanent magnets, and part of the rare-earth magnet family. Neo magnets have the highest magnetic properties, and are the most powerful commercially available magnets today. Because of their magnetic strength, neodymium magnets are the preferred choice for many.

NEODYMIUM MAGNETS - Allstar Magnetics

Some important properties used to compare permanent magnets are: remanence (Br), which measures the strength of the magnetic field, coercivity (Hci); the material's resistance to becoming demagnetized, energy product (BHmax), the density of magnetic energy, and Curie temperature (TC), the temperature at which the.

Unique Motor Uses Only Permanent Magnets – No Electric Power .

Nov 13, 2017 . Unless overheated or physically damaged, the magnet will lose less than 1% of its strength over 10 years. To see the impact of permanent magnets we have to look at a typical electric motor. As an external power source passes through the rotor field, it serves as an electromagnet that is attracted to the.
