Question

the core of an electromagnet can be made up of any metal. true or false

Answer 1

It is sheer false because the core must include such metal which easily gets magnetised such as pure iron.

Answer 2

The core of an electromagnet can be made up of any metal false

Explanation:

• The core of the electromagnet should made of certain metal which can further allow current to flow through it.
• Soft iron is used in magnetic assemblies, electromagnets and in some electric motors; and it can generate a concentrated field that is as much as 50,000 times more intense than an air core.  
• Iron is desirable to make magnetic cores, as it can withstand high levels of magnetic field without saturating, up to 2.16 teslas at ambient temperature.  
• It is also used because, unlike hard iron, it does not remain magnetized when the field is removed, which is often important in applications where the magnetic field is required to be repeatedly switched.
