Question

What are the factor to increase the Strength of an electromagnet​

Answer 1

Answer: Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.

Answer 2

Answer:

The factors which affect the strength of an electromagnet are as follows:---

i) It is directly proportional to amount of current flowing through it.

ii) It is directly proportional to the number of turns.

iii) If a rod of soft iron or steel is introduced as the core material inside the solenoid coil, then the magnetic field generated inside the solenoid increases by a large factor.

iv) The magnetic field of solenoid does not depend on dimensions of solenoid.
