21.2 Notes Electromagnetism is magnetism that results from electric current.Electromagnetism is magnetism that results from electric current. When charged particles, like electrons move, they produce a magnetic fieldWhen charged particles, like electrons move, they produce a magnetic field

21.2 Notes If a wire is shaped into a loop, the magnetism becomes concentrated inside the loop. The magnetic field is much stronger in the center of the loop than around a straight piece of wire. The more loops of wire, the stronger the magnetic field.

21.2 Notes A coil of wire with a current (electrons) flowing through has a magnetic field that is similar to a magnet.A coil of wire with a current (electrons) flowing through has a magnetic field that is similar to a magnet. The field flows in one direction and returns to the other end of the coil, which forms a north and south pole, just like a magnet.The field flows in one direction and returns to the other end of the coil, which forms a north and south pole, just like a magnet.
