His partner Catgut transforms from a four-legged beast into fusion-powered particle blaster with pulse demagnetiser attachment.

Nakamichi manufactured a "wand" type demagnetizer in the 1980s.

Regardless, he uses a demagnetizer in his suit to free himself, leaping forward and knocking Penguin's thugs out.

A demagnetizer?"

Another type of demagnetizer, the "wand" type can demagnetize anything that it is brought into contact with, including the tape heads and capstans.

They never need to be demagnetized, and if a cassette demagnetizer or similar device is used on such heads, the heads can be damaged or destroyed.

A cassette demagnetizer is a device that removes the magnetic field that is built up from the use of audio cassettes in a cassette deck.

In unusual cases of strong magnetization where the internal degaussing field is not sufficient, the shadow mask may be degaussed externally with a stronger portable degausser or demagnetizer.
