Ampere's Law

Help your class find the the magnetic field of a toroid, a solenoid bent into a circle with an activity that allows the class to see how a loop of wire carrying an electrical charge behaves much like a magnet. The resource provides the teacher information to develop a lecture on Ampere's Law, which in turn allows pupils calculate the magnetic field around a loop and a toroid.
