I'm working on some homework and am stumped with this problem. Help would be great, thanks!
A 5.0-cm-radius conducting loop with a resistance of 4.0 Ω is in the presence of a uniform magnetic field of strength 300 μT that is perpendicular to the plane of the loop as shown in the diagram below. The strength of the magnetic field is then decreased to 120 μT in a time of 0.10 s while the direction of the magnetic field remains constant. What current is induced in the conducting loop and what is its direction?
