In the figure below, the bar magnet moves toward a loop of diameter D, which is connected to a circuit with resistance R. As it moves closer to the loop, the magnitude of the magnetic field changes as |B(t)| = €₁ + C₂ t² + C3e¯ct, where c₂ are known positive constants. a) Find the direction of B magnet and the units of the constants C1, C2, C3, C4 b) What is the magnetic flux through the circular loop? c) Explain qualitatively and in detail the direction of the induced current (from point a to b, or from b to a in the figure) and the induced magnetic field. d) Calculate the Emf and induced current that appears in the system.
