Question
Two separate but nearby coils are mounted along the same
axis. A power supply controls the flow of current in the first
coil, and thus the magnetic field it produces. The second coil
is connected only to an ammeter. The ammeter will indicate
that a current is flowing in the second coil
(a) whenever a current flows in the first coil.
(b) only when a steady current flows in the first coil.
(c) only when the current in the first coil changes.
(d) only if the second coil is connected to the power supply
by rewiring it to be in series with the first coil.
