WebFeb 6, 2024 · Magnetization of Ferromagnetic Material using Rowland Ring (Toroid With Iron Core): The magnetization of a ferromagnetic material such as iron can be studied with an … WebThe jumping ring makes a metal ring jump up into the air using an electromagnet like the one described earlier. It is actually two electromagnets in one. Wire is wrapped around a base made of iron. The wire is connected to the electricity and when current flows in the wire, the iron becomes a very strong magnet. The second magnet is a metal ring.
