Como fazer um eletroímã? Como funciona?

Learn how to make an electromagnet and understand the basic working principle of a magnet created by electricity and a magnetic field. This magnet experiment energizes a coil with an iron core and demonstrates the final effect. A strong, powerful electromagnet can be achieved using high currents and purer, more specific materials in the core and coils. There are several practical applications for an electromagnet, including the famous electric locks, solenoids, relays, generators, motors, coils, and many others. In addition to the rare earths found in nature (elemental magnets, natural magnets), electromagnets can be created using electricity. This is how a magnet is made from various materials that are not originally magnets. Experiments with magnets are always very cool and seem like magic at first glance, but they are all explainable using the not-so-simple concepts of electromagnetism. Electrical installations.
