Question

write two ways to increase the strength of the field of a solenoid

Answer 1

Two ways to increase the strength of a solenoid are:
1) By increasing number of turns of insulated copper wire.
2)By increasing current in the circuit.
Hope this answer helps you

Answer 2

Explanation:

The magnetic strength in solenoid is given by formula :

$B=\mu\frac{N}{L}\times I$

B = Strength of magnetic field

N = Number of turns in solenoid

L  = Length of the solenoid

I = Current through the solenoid

$\mu$ = permeability

Two ways by which we can increase the strength of the magnetic field:

• By increasing the current in the solenoid.

• By increasing the number of turns in the solenoid.
