There is a coil in a plane of a page that contains 25 turns(loops). The diameter of the coil is 9.00cm and its resistance is5.0Ω. The coil is in a uniform magnetic field directed out of thepage. At t = 0, the magnitude of the field is 0.200T. The strengthof the field is increased at a constant rate for 10.0s until itreaches 2.20 T. It is held constant at that value for 9.00s. Thenit is decreased at a constant rate for 15.0s until it reacheszero.
1) Find the induced current in the coil at (i) t = 9.00 s, (ii)t = 15.0 s, (iii) t = 20.0 s?
2) At each of the times listed in the first part, if themagnitude of the current is non-zero, determine the direction ofthe current. (Apply to Lenz’s law.)
