Which description best applies to Lenz's Law?
An induced current occurs when a magnet passes through a tube.
When a change in magnetic field occurs to a coil the direction of current goes in the in the other direction to this change.
The direction of an induced current is such to align with the change that created it.
A magnet is a tube is always slowed by its magnetic field.
Which activity will produce the highest current?
Move the magnet bar into the coil while the coil remains stationery
Move the coil into the magnet bar while the magnet remains stationery
Move the coil and magnet towards each other
Move the coil and magnet away from each other
Which action will increase the deflection of the galvanometer pointer?
The magnetic pole is reversed
The number of turns of coils is increased
The coil is made from insulated wire
The magnet is slowly pushed into the coil
Name the following law: A changing magnetic field creates an electric current in a coil.
Ampere's Law
Faraday's Law
Lenz's Law
Coulomb's Law
Name the following law: A moving magnet creates an opposing magnetic field.
Ampere's Law
Faraday's Law
Lenz's Law
Coulomb's Law
Which side of the coil above will be north?
Right side
Left side
