The magnetic field that is oriented perpendicularly through a 9.2 cm diameter coil of wire drops from 6.4 T to 6.1 T in 0.076 seconds. What is the emf induced in the coil?
Trying to answer this. My question is, if they are perpendicular then does that mean that cos90 makes phi = BAcos theta become zero therefore making the emf zero when put into emf = -N delta phi/delta t ? That doesn't seem right?
