Hi,
I would like to know what would happen if you used a permanent magnet for the core of an electromagnet, instead of the standard ferromagnetic core? Can you increase the magnetic field strength of the permanent magnet by putting current through the coil? Also, could you effectively cancel the permanent magnet's field by reversing the current's direction?
Thanks
