Jumping Disc
When an electric current flows through a coil, it creates an alternating magnetic field. This magnetic field, in turn, induces a short-circuiting current in an aluminum bobbin. The resulting repulsion between the two magnetic fields causes the bobbin to jump upward. The magnetic force that propels the bobbin is strongest near the bottom of the coil and gradually weakens as it moves away. This magnetic dance showcases the dynamic interaction between electricity and magnetism, revealing a fascinating spectacle of science in action.
