There is a circular ring of wire. It has a radius α that carries a current in a counter clockwise direction L.P Part A) Reduce equation 10 to find the magnetic field at the center of the loop. Derive this answer from Ampère's Law Ho R2 401 (cos θ 10 B(z) Part B) Now let's assume it is an insulated circular disk with a uniform charge density σ is spinning at rate ω. Utilize Ampère's Law to determine the magnetic...
