Question

(ii) Mention two factors which affect the magnetic field produced by a straight current carrying conductor.

Hint:

When considering the magnetic field of a current-carrying conductor, remember that the magnetic field strength increases with current and decreases with distance from the wire.

Answer 1

The magnetic field produced by a straight current-carrying conductor is affected by the following factors: 1. Current Strength:
The magnetic field strength is directly proportional to the amount of current passing through the conductor. Higher current results in a stronger magnetic field.
2. Distance from the Conductor:
The magnetic field strength decreases as the distance from the conductor increases. It is inversely proportional to the distance from the wire. The magnetic field strength is stronger near the conductor and weaker farther away from it.
