What is the power put into the system by gravity

Reference no: EM13538879

A square loop with sides of 20 cm is falling through a magnetic field at v=5 m/s. The magnetic field is going into the page and is increasing as the loop falls farther through it. B = 3.0 T - 1.5 T * y. Also, the acceleration due to gravity is 9.8 m/s^2.

1) According to Lenz's law, determine the direction of the current within the loop.
2) Draw the direction of the magnetic force due to the magnetic field and the direction of the torque.
3) What is the power put into the system by gravity?
4) Find the resistance.
