Matters needing attention in using sucker electromagnet

Electromagnet is a device that generates electromagnetism by electrifying. A conductive winding matched with its power is wound around the iron core. The coil with current is as magnetic as a magnet. It is also called electromagnet. We usually make it into strip or hoof shape to make the iron core easier to magnetize. In addition, in order to make the electromagnet demagnetized immediately, we often use soft iron or silicon steel material with fast demagnetization. Such an electromagnet has magn
