• When charged particles, like When charged particles, like electrons electrons move, they produce a move, they produce a magnetic fieldmagnetic field

21.2 Notes21.2 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.
