Start Quiz
1.
According to Faraday's law the induced emf is proportional to
the flux linkage
the rate of change of flux linkage
the total flux
the resistance
2.
The flux through a 100-turn coil changes uniformly by 2.0 × 10−3 Wb in 0.040 s. The emf is
0.050 V
8.0 × 10−3 V
0.20 V
5.0 V
3.
A steady flux of large value passes through a coil. The induced emf is
zero
large
equal to the flux
alternating
4.
In a flux–time graph a steep negative gradient means
zero emf
a large emf of one sign
a small emf
no induced current
5.
A coil with twice the turns but otherwise identical sees the same flux change. The emf
halves
is unchanged
doubles
quadruples
6.
Which change does NOT induce an emf in a loop?
Moving the magnet toward the loop
Rotating the loop in the field
Holding a magnet still next to the loop
Changing the current in a nearby coil
