Question

Which factor will not affect the strength of a solenoid? 1) number of wraps2) strength of the current3) radius of the wraps4) core type

Answer 1

3) Radius of the wraps

Step-by-step explanation

We want to find the factor that will not affect the strength of a solenoid.

A solenoid is an electromagnet and there are four factors that mainly affect the strength of an electromagnet:

1) The wire size;

2) The number of loops/turns;

3) The current;

4) The presence of an iron core.

Therefore, the correct option is the radius of wraps/turns (option 3) since it does not affect the strength of a solenoid.
