Question

The strenght of the magnetic field produced by a solenoid can be altered by changing the ??

Answer 1

1) By increasing/decreasing the amount of current
2) By increasing/decreasing the number of turns of coil
3) By using a soft core within a solenoid

Answer 2

Answer:

The strength of the magnetic field produced by a solenoid can be altered by the _____________.
(a) direction of current

(b) magnitude of current

(c) number of turns in the coil

(d) both (b) and (c)

Explanation:

The strength of the magnetic field produced by a solenoid can be altered by 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.
