Question

The value of intensity of magnetic field
at a point due to a current carrying
conductor depends
Only on the value of current
O
Only on a small part of length of
conductor
On angle between the line joining the
given point to the midpoint of small length
and the distance between the small length
of the point
O
On all of the above​

Answer 1

Explanation:

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.
