Abstract: The physical characteristics of the oscillation can be predicted by building two models under different conditions.Three typical modes of oscillation are determined by three initial conditions and be verified by simple but complete experiments.Some related phenomena and characteristics are discussed later in order to deepen the comprehension of coupling oscillation.

Key words: magnetic needle, magnetic charge, magnetic dipole, coupled oscillator, compass
