Question

What is an electromagnet? Mention two properties of an electromagnet​

Answer 1

Answer:

two properties of electromagnet are : ... The Strength of the electromagnets can be increased by increasing the current in the coil. 2. The Strength of the electromagnet can be increased by introducing a soft iron core inside the coil.

Answer 2

Answer:

$\textbf\color{red}{Electromagnet }$

An electromagnet is a temporary magnet which is formed by passage of electric current and the magnetic field is included as long as the current is passed through the circuit. It works on the magnetic effect of current.

$\textbf\color{red}{Properties of an electromagnet are:-}$

• The magnetism of the soft iron is not permanent and is lost as soon as the flow of current is switched off.
• The magnetic field of the electromagnet can be changed when required. The strength of the electromagnet depends on the following three factors.

✨The nature of the material of the core

✨The total number of turns of the coil

✨The strength of the current passing

through the coil
