Auniform non-conducting ring of radius 2.2 cm and total charge 6.08 µc rotates with a constant angular speed of 2.01 rad/s around an axis perpendicular to the plane of the ring that passes through its center. what is the magnitude of the magnetic moment of the rotating ring?

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

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
