A. Course Overview
A magnet gives rise to a field that surrounds them and which causes forces on other
magnets, iron and steel objects, and current- carrying wires. The part of a magnet
where the field emerges is called the N pole, and where the field enters the magnet is
called the S pole. Magnets always have both N and S poles.
It takes energy to make a magnetic field. We can use this idea to explain the magnetic
force. When we turn off the current to an electromagnet, the magnetic energy will
keep the current going briefly, and in the process may give rise to an unusually high
voltage in the circuit or even a voltage in a different circuit.
Electricity is related to magnetism in several ways. A current gives rise to a magnetic
field, and a magnetic field gives rise to a force on a current. A rapidly changing
magnetic field gives rise to an electrical effect that will make currents flow.
B. Course Objective
