What happens when a permanent magnet is wound with a copper wire

[270000]

what happens when a permanent magnet is wound with a copper wire (inductor) and the inductor is connected to some volatge? Will the magnetic flux of the permanent magnet increase (i.e., make the permanent magnet more strong)?

Depends on which way the current is flowing. It can add or subtract. I don't know what the effect is on permanent magnets thought. It might destroy their natural magnetism.

It will increase or decrease, as was said, but by how much depends on the magnetic hardness of the material, its hysteresis curve, and the current. If the material is very hard, and the current is weak, the change will be very small.
