There are more magnetic materials in the north.
That is the only directionin which it can point.
It is repelled by the South Pole.
It aligns with Earth's magnetic field.
Near the north pole
Near the south pole
Near both poles
Near the middle
Two half magnets.
Always a magnet.
A magnet if its domains are aligned.
A magnet if its domains are not aligned.
Never a magnet.
Decrease the voltage.
Increase the voltage.
Increase the magnetic field strength.
Decrease the magnetic field strength.
Making the loops smaller in the coil
Placing an iron bar in the coil
Winding more loops in the coil
Increasing the current in the coil
Electrical energy into mechanical energy.
Power into energy.
Mechanical energy into electrical energy.
Energy into power.
It has no effect.
It pulls the charge forward.
It pushes the charge backward.
It pushes the charge perpendicularly to the field and the charge's velocity.
