Physics

A coil lying in the plane of the page contains 40 turns (loops).The diameter of the coil is 5.00cm and its resistance is 12.0Ω. Itis in a uniform magnetic field directed out of the page. At t = 0,the magnitude of the field is 0.800T. The strength of the field isincreased at a constant rate for 10.0s until it reaches 1.50 T. Itis held constant at that value for 5.00s. Then it is decreased at aconstant rate for 15.0s until it reaches zero.

1) What is the magnitude of the induced current in the coil at(i) t = 5.00 s, (ii) t = 12.0 s, (iii) t = 20.0 s?

2) At each of the times listed in part (a), if the magnitude ofthe current is non-zero, determine the direction of the current.You should describe your application of Lenz’s law
