Question

what is electromagnet name the factors on which the strength of an Electromagnet depends​

Answer 1

Electromagnet is a soft iron core which when placed inside a solenoid, behaves like a powerful magnet Whenever a current is passed through the solenoid. The iron core loses it's magnetism when the current is switched off, and it behaves no longer as electromagnet. Therefore they are also called temporary magnets.

Factors on which strength of an electromagnet depends :-

(i) Number of turns in the coil - the larger the number of turns in the coil, greater is the strength of electromagnet
(ii) Strength of the current - the larger the current is passed through the solenoid,more powerful is the electromagnet.
(iii) Nature of the core material - the core of the magnetic material like soft iron increases the strength of the electromagnet.

Answer 2

ANSWER: Sample Response: To make an electromagnet stronger, more coils can be added to the solenoid, a greater amount of current can be sent through the solenoid, and a larger or more magnetic piece of metal could be used in the core.
