Electromagnet

The model demonstrates a simple **electromagnet**, a type of magnet that can be turned on and off, unlike permanent magnets, which retain their magnetism continuously. Electromagnets function through electricity and are magnetic only when electric current flows through them. When electric current passes through the wire, it generates both an electric and a magnetic field. The resulting electromagnet can be strong enough to lift objects like paper clips. Once the current is turned off by disconnecting the wires from the battery, the paper clips are released and fall. In 1820, Danish physicist Hans Christian Ørsted discovered the fundamental relationship between electricity and magnetism. Through his work and subsequent research of others, we can now create powerful magnets using electricity, with the ability to control them to pick up and release objects at will. Electricity and magnetism are intrinsically linked. The movement of electrons generates both phenomena, and every electric current creates its own magnetic field. This magnetic force can be harnessed to produce powerful electromagnets, which can be easily switched on and off.
