1 answer
Putting a magnet through a coil of conducting wire: This demonstration shows the effect of electric current on a magnet as the movement of the magnet inside the coil induces an electric current, which in turn creates a magnetic field that interacts with the magnet. This is known as electromagnetic induction and demonstrates the relationship between electric current and magnetism.
