Question

what is the middle magnet?

Answer 1

The opposite end is called the south pole. The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strongmagnet. ... The rule for magnetic poles is that like poles repel each other and unlike poles attract each otherThis shows the field lines around a disk magnet where the North pole is at the top. This shows the magnetic field strength around the disk magnet. Again, it is strongest in the corners, not in the center of the poles! The magnetic field is weakest in the middle of its poles!
