A circular coil that has 95 turns and a radius
of 16 cm is in a magnetic field that has a magnitude
of 0.0650 T directed perpendicular to the coil.
(a) What is the magnetic flux through the coil?
Wb
(b) The magnetic field at the coil is increased steadily
to 0.100 T over a time interval of 0.5 s. What
is the magnitude of the emf induced in the coil during the time
interval?
V
