Abstract

The behavior of compass needles in the Earth’s magnetic field was introduced in Chapter 1 to present the concept of magnetic resonance. A compass needle is actually a small bar magnet which oscillates at a particular frequency when driven from its resting state. The frequency of its oscillation is proportional to the field strength in which it finds itself. While the simplest means of stimulating a compass needle is by a simple tap of the finger, it can also be driven from its resting state by subjecting it to an alternating external magnetic field. When the alternation occurs at the needle’s natural or resonant frequency, the compass needle absorbs energy.
