21.2 Notes CURRENT can produce MAGNETISMCURRENT can produce MAGNETISM

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.
