Homework Statement

Textbook problem 29.48 on changing magnetic field: coil on a table tilted 30.0 degrees, field (0.120 T)(1 - cos pi t) then 0.240 T after 1.00 s, asks for graph of current and direction.

Homework Equations

That is my solution:

Worked solution showing induced emf equations for a coil, followed by a sketched graph of current I against time t rising to a peak of 0.259 mA at 0.5 s and returning to zero at 1.0 s.

The Attempt at a Solution

i solve my problem without ø=30°, I confused what this angle was used to do?

Think about what your first formula is actually saying. It the rate of change of the flux through the coil. If the table was flat would there be any flux through it?
