Arc magnets can be used in a wide range of fields. Especially the electrical industry. Electrical appliances bring us a lot of convenience in life, among which arc magnets play an indispensable role. In order to make a ring magnet, we need to put the magnet in a container, and then surround it with magnets of different shapes and sizes. The magnets repel and repel each other to generate a magnetic field around the container. If the magnet moves along this magnetic field, it will pull itself along the path of the magnet, causing it to move.
