Q1. A rectangle loop is placed in a region of uniform magnetic field with a magnitude B. The magnetic field is perpendicular to the plane of the loop and is pointing inwards (see diagram). (20 points) B x X x x x x x 5.0 cm x x x x x x x 2.0 cm a) If the magnitude of the B-field changes at a constant rate from B₁ = 2.4 T to B₂ = 4.8T, find the change in magnetic flux (Ap). b) If the change in flux takes t = 2s, find the magnitude of the emf and the direction of the induced current. ton c) Now instead of changing the magnitude of the magnetic field (keeping it constant at B₁ = = 2.4 T), if you want to produce the same emf (as in part b), in what velocity should you move the loop in x-direction. d) If the resistance of the wire is R = 602, find the magnitude of the induced current
