Electromagnets are made by coiling or wrapping wire around a core. When an electrical current passes through the wire, a magnetic field forms, which can be used to exert force or drive motion. Ferromagnetic materials are either repelled or drawn to the magnetic field, depending on the polarity of the electromagnet. The force stops when the current is switched off.
By adjusting the current, users can control the polarity, duration, strength, and magnetism of the electromagnet. By controlling the magnet remotely, operators can activate critical components in robotic systems, making it easier to handle goods safely and efficiently while reducing the risk of product damage, contamination, or bodily injury.
