1.
Lenz's law is a consequence of the conservation of
charge
momentum only
mass
energy
2.
The north pole of a magnet is pushed toward a coil. The nearest end of the coil becomes
a north pole
a south pole
neutral
a source of no field
3.
Flux into the page through a loop is increasing. The induced current is
clockwise
anticlockwise
zero
either, depending on the area
4.
A magnet falls through a copper tube more slowly than through a plastic tube because
copper is heavier
plastic is magnetic
eddy currents oppose its motion
air resistance is larger in copper
5.
Laminating a transformer core reduces
the number of turns
the flux density
eddy current losses
the output emf at no load
6.
The minus sign in Faraday's law represents
the induced emf opposing the change in flux
a decrease in flux
a negative charge
energy lost to heat
