In the figure shown, what would happen if the direction of the current in the wirecoil was reversed
The electromagnet would no longer work
The north and south poles would switch places
The strength of the magnetic field would increase
The strength of the magnetic field would decrease
Which is the best prediction for what will happen to the reading on the meter when the magnet stops and then is moved down through the loop of wire?
The reading will not change
The reading will drop to zero and then return to the same reading.
The reading will drop to zero and then move in the negative direction
The reading will drop to zero and remain there.
Changing _ of the current in a wire could reverses an electromagnet's north and south poles
(a)
which statement is false?
The direction a magnet moves through a coil of wire determines the direction of the electric current.
The direction a coil of wire moves through a magnetic field determines the direction of the electric current.
Current will flow through a wire as long as the magnetic field around the coil is changing.
Current will not flow through a wire if the magnet is outside the coil.
Which statement is true?
As the electric current through a wire increases, the magnetic field around the wire becomes stronger.
As the electric current through a wire increases, the magnetic field around the wire becomes weaker
As the electric current through a wire increases the magnetic field around the wire is unaffected
As the electric current through a wire increases the magnetic field around the wire becomes stronger.
