Question

Name the two factors on which the magnitude of the magnetic field due to a current carrying coil depends.

Answer 1

The magnitude of the magnetic field due to a current-carrying coil depends on the amount of current flowing through the coil and the number of turns in the coil.

Here the factors are explained clearly below:

• Current: A higher current flowing through the coil will produce a stronger magnetic field.
• Number of Turns: Increasing the number of turns in the coil also strengthens the magnetic field, as the individual magnetic fields from each turn add up to create a stronger overall field.

Answer 2

Factors on the magnitude of the magnetic field due to a current-carrying coil depend:

1. Number of turns in the coil.
2. Strength of the current flowing through the coil.
