Lots of reasons. It might be in a car.

When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
What is inside a generator that makes electricity?
Coils of wire and a magnet. When magnetic lines of force move across a wire, it causes electrons in the wire to move. Those moving electrons are electrical current. In a generator, either the magnet or the coils of wire spin.
What is the condition that is necessary for a charge to move in a wire?
A device to get a current flow through a wire (i.e. from a battery) and no breaks in the wire.
When a magnetic field is used to create an electric current in a wire?
The magnetic field must be changing relative to the conductor (wire). So the wire could move through the field, or the field could move past the wire, or you could have a changing field (from an electromagnet with varying current).
Which wire would have the least resitance a large diameter or small diameter wire and why?
large diameter wire simply because it will move easier Technically they would have the same resistance, but the larger diameter wire would allow more current to flow as it would have more room to move.
What is needed in order for electricity to move from the source to a hairdryer?
A wire.
How do you make current?
Move the wire through a magnetic field
What must move in a coil of wire to make electricity?
A conductor
What does voltage cause?
The ability of current to move through a wire.
Car shut down after open AC?
look under the hood and rev. your engine the piece that moves is the throttle on the throttle there is a wire you need to take the wire and move it back so there is more wire exposed just grab the wire with a clamp and move the throttle up and you should be fine.
How do you transfer 40kph mechanicall energy into electrical energy?
The usual method to convert mechanical energy into electrical energy is to move a wire in a magnetic field (or alternately, move the magnet near to a wire).
What two things are needed to make electrons move along a wire?
-- voltage difference (electromotive force) between the ends of the wire; -- conductive substance comprising the wire.
