CAn you pls. exp. me the horshoe magnet's experiment.

Dear student,

Every object has a natural frequency of vibration. If kinetic energy is applied to an object at a rate that matches its natural frequency, resonance occurs and the object vibrates. In this  experiment  a small current, produced by a signal generator, causes the  sonometer wire to move up and down due to interaction with the magnetic field of a horse shoe shaped magnet. When the frequency of the a.c. current matches the fundamental frequency of the wire, resonance occurs causing noticeable vibration.

Hope this is clear.

Regards
