A loop of wire sits in a uniform magnetic field, everywhere
pointing toward you. Due to a changing magnetic flux through the
loop, an induced current flows in the wire, clockwise as shown. The
area of the loop is 1.94 m2, and the magnetic field initially has
magnitude 0.48 T.
(a) Suppose that, over a time period of 1.34 s, the magnetic
field changes from its initial value, producing an average induced
voltage of 8.0 V. What is the final...

A 15-cm diameter circular wire loop spins at 250 rpm on an axis parallel to a 750-T magnetic field. Write an expression for the emf induced in this loop as a function of time. Include numbers in your expression wherever possible, and don't worry about getting the formula formatting exactly right. (Also, you may assume the initial magnetic flux to be zero if it makes this problem easier for you.)
