Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
An e.m.f. is induced in a coil when
the field is parallel to the coil
the flux linkage is large
the flux linkage changes
the coil carries current
2.
A magnet is held at rest inside a coil. The voltmeter reading is
zero
alternating
negative
large and constant
3.
A 0.50 m wire moves at 2.0 m s−1 perpendicular to a field of 0.040 T. The induced e.m.f. is
0.50 V
0.040 V
0.020 V
0.080 V
4.
Which change will NOT increase the e.m.f. induced when a magnet is pushed into a coil?
More turns on the coil
Stronger magnet
Faster motion
Using a thicker wire of the same turns
5.
A wire moves parallel to the field lines. The induced e.m.f. is
half the maximum
dependent on its resistance
maximum
zero
6.
Induction obeys energy conservation because
energy is created in the coil
the induced current opposes the change causing it
the magnet loses mass
the field strengthens
