Hall-Effect Sensors

Hall-Effect Sensors Based on the principle that if a current is allowed to flow through thin conducting material that is exposed to a magnetic field, another voltage is produced. The switch contains a permanent magnet, a thin semiconductor layer made of gallium arsenate crystal (Hall layer), and a shutter wheel. The Hall layer has a [...]

Decrypt NdFeB Magnets

Decrypt NdFeB Magnets - The formation of a magnetic field is a magnetic field generated by a molecular ring current of a magnetic substance, and the direction of movement of atoms or ions outside the nuclear electrons is random, so a large number of atom synthesis current is zero, no magnetic field, such as ferric [...]

Do permanent magnets have a half-life or otherwise “decay” over time?

Do permanent magnets have a half-life or otherwise “decay” over time? from reddit Physics It seems like there must be some energetic cost to constantly exerting a force on the surroundings. As particles & objects resist that force, it must exert some backward torque or whatever on the aligned atoms of the magnet. Over time, [...]

Permanent Magnet Stability

Permanent Magnet Stability Permanent Magnet Stability - The ability of a permanent magnet to support an external magnetic field results from small magnetic domains "locked" in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The [...]
