A magnetic field is perpendicular to a 0.060 m 0.060 m rectangular coil of wire that has 100 turns. In a time of 0.070 s, an average emf of magnitude 1.5 V is induced in the coil. What is the magnitude of the change in the magnetic field?
My professor has not covered this in lecture yet, but this HW is due tomorrow. Reading the section for myself and looking at the equations, this is what i have come up with so far. Please help me out, thanks.
average induced emf=magnetic flux/time
average induced emf=B(Area)/time
average induced emf=-N(magnetic flux)/Time
Where do i start?
