Solution: We have, Area(A)=πr2 Where, radius(r)=1.80×10-3 m Therefore,…

A magnetic field is uniform over a flat, horizontal circular region with a radius of 1.80 mm, and the field varies with time. Inițially the field is zero and then changes to 1.50 T, pointing upward when viewed from above, perpendicular to the circular plane, in a time of 140 ms.
