1) A coil of wire with 80 turns and a cross-sectional area of .03m^2 lies perpendicular to a magnetic field of magnitude 1.5T. The coil is rapidly removed from the magnetic field in a time of .1s
a) what is the magnetic flux through the coil?
b) what is the average value of the voltage induced in the coil?
c) what is the average value of the voltage induced in the coil if it is rapidly put back into the field in a time of .1s?
2) A transformer has 20 turns of wire on its primary coil and 80 turns of wire on its secondary coil.
a) is this a step-up or step-down transformer?
b) if an altering voltage of 110V is applied to the primary, what is the voltage induced in the secondary?
c) if 6 A of current are supplied to the primary coil, then what is the effective currrent in the secondary coil?
