Ohm’s law — How a lifting magnet work


Industrial Lifting Magnets are very simple machines. They are nothing more than a string of wire wrapped around a magnetic core. This string of wire has resistance (ohms) that govern what current (amps) flows at a given voltage (volts). All DC magnets obey Ohm’s law. A magnet at room temperature, or ambient temperature, has the […]

Lifting magnets transport steel and scrapped vehicles in industry


A lifting magnet does exactly what it says: it’s an electromagnet that can pick up or lift metal objects. A lifting magnet has magnetic properties in its electrified coil and is normally attached to a crane. The crane then positions the magnet above the objects and the magnet is energized. Lifting magnets vary in size. […]
