Question

Relative strength of magnetic field at a point in the space surrounding the magnet is shown by the?

Answer 1

Answer:

degree of closeness of the field

Answer 2

Relative strength of magnetic field at a point in the space surrounding the magnet is given below.

Explanation:

Here magnetic is electro magnet.

Relative field of magnetic field is

               ⇒ B = $\frac{uI}{2\pi r}$

where,

       B  is the strength of the magnetic field.

       u is the permeability of the free space in the air.

       I is the magnitude of the electric current which leads to generation of magnetic field.

       r is the distance between the point in space and the magnet.
