2. Explosively pumped flux compression generator - Wikipedia

   en.wikipedia.org/wiki/Explosively_pumped_flux...

   The magnetic flux threading the ring, represented by five field lines, is reduced by the same ratio as the area of the ring. The variation of the magnetic flux induces a current (red arrows) in the ring by Faraday's law of induction, which in turn creates a new magnetic field circling the wire (green arrows) by Ampere's circuital law. The new ...

3. Alnico - Wikipedia

   en.wikipedia.org/wiki/Alnico

   Alnico's remanence (B r) may exceed 12,000 G (1.2 T), its coercivity (H c) can be up to 1000 oersteds (80 kA/m), its maximum energy product ((BH) max) can be up to 5.5 MG·Oe (44 T·A/m). Therefore, alnico can produce a strong magnetic flux in closed magnetic circuits, but has relatively small resistance against demagnetization.

4. Eddy current brake - Wikipedia

   en.wikipedia.org/wiki/Eddy_current_brake

   Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

5. Superconducting magnetic energy storage - Wikipedia

   en.wikipedia.org/wiki/Superconducting_magnetic...

   Needed because of large Lorentz forces generated by the strong magnetic field acting on the coil, and the strong magnetic field generated by the coil on the larger structure. Size. To achieve commercially useful levels of storage, around 5 GW·h (18 TJ), a SMES installation would need a loop of around 800 m. This is traditionally pictured as a ...

6. Permanent magnet motor - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet_motor

   Strontium carbonate and iron oxide, also known as a “ceramic” or “ferrite” magnet, is a NRE permanent magnetic material found in permanent magnet motor applications such as power tools, industrial magnetic separation processes, and automotive sensors. Ceramic magnets are significantly weaker than either SmCo or NdFeB but are generally ...

7. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   Ferrite magnets find applications in electric power steering systems and automotive sensors due to their cost-effectiveness and corrosion resistance. [37] Ferrite magnets are known for their high magnetic permeability and low electrical conductivity, making them suitable for high-frequency applications. [38]
