The figure below shows a circular conducting loop with a 4.70-cm radius and a total resistance of 1.10 Ω placed within a uniform magnetic field pointing into the page.
(a) What is the rate at which the magnetic field is changing if a counterclockwise current
I = 4.70 ✕ 10^−2 A
is induced in the loop? (Give the magnitude.)
(b) Is the induced current caused by an increase or a decrease in the magnetic field with time?
