Why are we not use steel in electromanet |
|
Answer» We do not use steel as an electromagnet because when we stop supplying current, it does not loose its magnetic power and will react as a magnet. The core of an electromagnet is made of an iron alloy known as soft iron. This nearly pure iron is preferred because it doesn’t have a remaining magnetization after the current stops, unlike most steels. This material also has higher magnetic permeability which increases the force of the electromagnet. |
