Electricity
Electric current does not pass easily through...
What is insulators?
The space around a magnet where magnetism acts.
What is the magnetic field?
A circuit with objects connected in a single path.
What is a series circuit?
A tiny bit of an atom that has a postivie charge.
A magnet made when an electric current flows through a wire.
What is an electromagnet?
How well electricity flows through an object.
What is resistance?
An object that pulls iron and steel things to it.
What is a magnet?
A circuit in which current has a separate path of each object.
What is a parallel circuit?
A tiny bit of an atom that has a negative charge.
What is an electron?
The north pole of a magnet pulls this pole of another magnet.
What is the south pole?
Electric current passes easily through...
What is a compass?
A kind of circuit you would need to have one light bulb on and one off?
What is a parallel circuit?
What is a negative charge?
A wire made into loops, the magnetic field that is made when electric current flows through the wire is...
What is stronger?
A machine that uses that uses an energy source and a magnet to make electricity.
What is a generator?
A place on a magnet that is the strongest.
A circuit would cause all the lights on it to go out if one light went out.
What is a series circuit?
Explain how an object gets a negative charge.
When two objects rub together, they electrons can be passed from one to another.
Metals are good...
Why does an electric generator need a source of energy?
They do not make their own energy. They use stored energy.
The force around a magnet.
An electric current can only flow through this kind of circuit.
What is a closed circuit?
When a cloud becomes overcrowded with electrons, this happens.
What is lightning?
Shutting off the circuit when the wires become too hot.
