Can you temporarily reverse or weaken a permanent magnet's field with a coil?

[DUST 12]

Found one article saying it is possible to reverse poles of permenant magnet using coiled wire wrapped around magnet, but nothing about the possibility of temporarily reversing or even temporarily weakening the magnetic field.. if there are any magnetism connoisseurs out there..

Coercivity

That's how the magnet factory in my town makes them permanently magnetized.

An old fashioned soldering gun will reverse a hand compass.

Try it. One experiment is worth a thousand expert opinions.
