Electromagnet

The model demonstrates a simple electromagnet, which can be turned on and off unlike permanent magnets. It operates on electricity, creating a magnetic field only when powered. This electromagnet can lift paper clips when activated but releases them when the power is cut. Discovered in 1820 by Hans Christian Oersted, the link between electricity and magnetism allows us to create and control powerful electromagnets using electricity, offering versatility in attraction and release with the flip of a switch.
