Homework Statement



The 2-cm (radius) current loop shown in the figure is changing from θ1 = 11 degrees to θ2 = 66 degrees in a magnetic field 2 T in 0.5 seconds. What is the magnitude of the induced emf to the nearest hundredth of a millivolt.

The wire in Problem 2 has a thickness of 1.04 mm and a resistivity of 1.71 x 10-8 Ωm. To the nearest tenth of a milliamp what is the induced current in the loop

You need to show some more work. Show us how you calculate the change in the flux through the loop as it moves through that angle change.... Also, in your first relevant equation, you're using F for flux, not force, right?
