Rotating current carrying loop

Consider a circular loop of wire fixed on the rim of a wheel. This wire carries a current 'i' in it. When the wheel is at rest, which basically means that the current carrying loop is at rest, the magnitude of magnetic field at the center is, say B1. If I set the wheel in motion with a constant angular velocity with the center of the wheel at rest and without changing the current in the loop, which implies that the current carrying loop rotates about its center point, will the magnitude of magnetic field change at the center point?

I think that it will change because number of charges passing through a unit cross section which is at relative rest with respect to the center point changes and hence current effectively changes and hence magnetic field changes. Is this correct?

• Is the magnetic field due to charges or is it applied if it is due to current carrying loop then we see that initially also the loop Carrie's a current and finally also it is carrying a current . The affect of rotation in frame of wheel will cancel out as both the centre and rim have acquired w . Kindly confirm which field are you talking about Commented Oct 12, 2020 at 11:26
• The magnetic field is due to the charges moving inside the conductor. Commented Oct 12, 2020 at 11:51
• @anusha I think "bicycle" wheel made this a bit unclear. It's just a current carrying loop rotating around it's center with the center at rest. Will the magnetic field change ? Commented Oct 12, 2020 at 11:55
