Which of the following best explains why the magnetic field within a solenoid can be quite large?

Question

Group of answer choices

The magnetic field is the sum of the fields in each individual loop.

The domains of the iron are aligned by the magnetic field of the current.

The force between two north poles in each individual loop creates attractive forces.

The magnetic field within a solenoid is actually quite small.

Answer 1

The best explanation for why the magnetic field within a solenoid can be quite large is:

The magnetic field is the sum of the fields in each individual loop.

In a solenoid, each loop of wire contributes to the overall magnetic field, and when many loops are wound together, their individual fields combine, resulting in a strong, uniform magnetic field inside the solenoid.
