Question

a magnet that is hard to magnetize

Answer 1

Answer:

Permanent Magnets are the magnets that are hard to magnetize as their atomic magnetic domains aren't easily aligned ,but once aligned they remain so indefinitely.

Hope this helps

Answer 2

When domain wall is difficult to migrate, magnetization of the ferromagnetic material occurs only when high magnetic field is applied. In other words, this type of ferromagnetic materials are difficult ot magnetize, but once magnetized, it is difficult to demagnetize.
