Chapter 17, Section 1: Nature of Electromagnetic Waves
... • When a particle changes its motion, its magnetic field changes. This also causes the electric field to change. When one vibrates, so does the other. The result is an electromagnetic wave. ...

... F-11. Two loop of wires labeled A and B are placed near each other as shown. A large current I in loop A is suddenly turned on. This causes an induced current in loop B which causes A) A net replusive force - the two loops repel B) A net attractive force - the two loops attract C) whether the force ...

... When a magnetic compass is held near a wire carrying an electric current, the compass needle is deflected and this shows that there is a magnetic field near the wire. The field near a straight wire is too weak for most purposes, but if the wire is wound into a coil, the same current will produce a m ...
