# A current circulates around a diameter superconducting ring. a. What is the ring’s magnetic dipole moment? b. What is the on-axis magnetic field strength from the ring?

a. The ring magnetic moment is

b. the magnetic field strength is

See the step by step solution

## Part (a) Step 1: Given information

We have given,

current =

Diameter =

We have to find the magnetic dipole moment.

## Step 2: Simplify

The magnetic dipole moment of ring is

## Part (b) Step 1: Given information

We have given,

Distance =

We have to find the magnetic field strength.

## Step 2: Simplify

Magnetic field due to dipole is
