Question

Name the factors on which the magnetic field produced by a current-carrying conductor depends.

Answer 1

The magnetic field produced by a current-carrying conductor depends upon:

1. The amount of current flowing through the conductor: Larger the current flowing through the conductor, the stronger the magnetic field produced and vice-versa. $F\propto IwhereI=currrent$
2. The distance of the point ( at which magnetic field is to be found) from the conductor: The larger the distance from the conductor, the weaker the magnetic field and vice-versa. $F\propto \frac{1}{r}wherer=dis\tan ceofthepointfromtheconductor$
