Question

Give the factors that affect strength of magnetic field at a point due to a straight conductor carrying current

Answer 1

1. Amount of current carrying by the coil.
2. Magnetic field is inversely proportional to square of the distance of the point of observation

Answer 2

The magnetic field at a point due to a straight conductor carrying current depends on :

Current and distance from wire

Explanation:

The magnetic field at a point due to a straight conductor carrying current is given by :

$B=\dfrac{\mu_o I}{2\pi r}$

I is current passing through wire

r is distance from wire

It is clear that the magnetic field at a point due to a straight conductor carrying current is directly proportional the current and inversely proportional to the distance from wire.
