Question

How does the strength of the magnetic field produced change:

(i) with the distance from the conductor?

(ii) with an increase in current in a conductor?​

Answer 1

Answer:

Magnetic field strength is inversely proportional to the distance from the wire i.e. \begin{align*}B \propto \frac{1}{r}\end{align*}, greater the distance from the current carrying conductor, weaker will be the magnetic field
