Answer:
The magnitude of the magnetic moment of the rotating ring is
Explanation:
Given that,
Radius = 2.2 cm
Charge
Angular speed = 2.01 rad/s
We need to calculate the time period
Now, The spinning produced the current
Using formula for current
We need to calculate the magnetic moment
Using formula of magnetic moment
Put the value of I and A into the formula
Put the value into the formula
Hence, The magnitude of the magnetic moment of the rotating ring is
