Speakers have magnets in them because they help produce sound using electromagnetism. Magnets inside a speaker create a varying magnetic field when exposed to electric current. This creates an electromagnetic force that forces the speaker''s driver to move back and forth. Because the driver is attached to the speaker''s cone, it is subject to ...
Now let us start discussion about energy stored in the magnetic field due to permanent magnet. Total flux flowing through the magnet cross-sectional area A is φ. Then we can write that φ = B.A, where B is the flux density. Now this flux φ is of two types, (a) φ r this is remanent flux of the magnet and (b) φ d this is demagnetizing flux.
The Inductrack is a specific type of EDS that uses permanent room-temperature magnets to produce the magnetic fields. Typically the magnets used for EDS need to be super cooled which saves more energy. The newer material in Inductrack also creates stronger magnetic fields which leads to more extreme levitation.

In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. "A Maglev train car is just a box with magnets on the four corners," says Jesse Powell, the son of the Maglev inventor, who now works with his father.
