I have an electromagnet powered by a car battery charger set at 12 volts. The problem is the electromagnet won't repel the neodymium magnet however it is strong enough to pick up a wire strippers. I tried changing the polarity of the electromagnet by switching the leads going from the battery charger to the electromagnet, also I tried turning the magnet around so its other pole would be facing the electromagnet and I tried placing the magnet at the other end of the electromagnet. However nothing seems to works. So I'm wondering does anyone know what I'm doing wrong?
Is the Neodymium magnet shaped like a bar magnet?
Float the electromagnet on water and approach the neodymium magnet from various angles and see it the electromagnet rotates.
The charger does that produce a continuous current or an alternating current? Or is it pulses of current" When there is no current the core of your magnet could be attractive to your neodymium magnet. What is the core made of?
