As it turns out, the ability to nullify the powerful magnetic field from a bunch of rare earth permanent magnets is as simple as bringing in another set of magnets to cancel out the magnetic ...

In fact, the discovery actually supports a key part of the theory about how chorus waves work. Using data from the ...

It revolutionized the low-cost mass production of permanent magnets and ... coercivity — a measure of a magnet’s resistance to other strong magnetic fields,” explains Sagawa.
