WebElectromagnetic induction A magnet and a coil of wire can be used to produce an electric current. A voltage is produced when a magnet moves into a coil of wire. WebElectromagnets. A coil with an iron core is called an electromagnet.. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail.

WebTransformers use electromagnetic induction to change the voltage of alternating currents. The voltage and current changes can be calculated, as the power transfer is constant. Part of WebElectromagnetic induction can occur in a coil when the current in a neighbouring coil changes. This is called mutual induction and is the principle behind transformers, which are used to...
