How to Demagnetize a Magnet

How to Demagnetize a Magnet Permanent magnets require special manufacturing techniques in a magnetic field to get the metal to stay in the proper alignment. In order to demagnetize a magnet, you need to change this alignment. This process usually requires a high amount of heat, or a strong magnetic field at a reverse polarity [...]

Br Magnetic Question

Br Magnetic Question - The magnet I ordered has a Br spec of 12.4 kG - why is the flux density only measuring 3.0 kG? This is best explained through referencing the permanent magnet characteristic of permeance coefficient, which is strictly determined by geometry. In general, longer magnets have greater permeance coefficients. Additionally, a magnet [...]
