The most suitable material to be used as the core of an electromagnet is __________ .
The most suitable material to be used as the core of an electromagnet is __________ .
Open in App
Solution
The correct option is C Steel
The core of an electromagnet is made of an iron alloy known as soft iron. This nearly pure iron is preferred because it does not have a remaining magnetized after the current stops, unlike most steels. This material also has higher magnetic permeability which increases the force of the electromagnet.Hence, option : B.
