What is Magnetism?
The sides of a magnet that attract to each other
What is North and South?
A temporary magnet created when there is a current in a wire coil
What is an electromagnet?
This is what provides most of the energy that you use everyday
What is a generator?
What the earth's core is made up of
Iron and Nickel
The region of a magnet that exerts the strongest force.
What is turbine?
Who are the Greeks?
This is how to make a electromagnet
what is running an electric current through a coil?
This is the thing that both generators and electric motors use to convert electrical and mechanical energy
What is an electromagnet?
Groups of atoms with aligned magnetic poles.
What is magnetic domain?
The way compasses interact with magnets
What is by following the magnetic field lines?
The attraction or repulsive force between electric charges and magnets.
What is an electromagnetic Force?
This is the output in a setup transformer when the input is 60 volts
What is 120 volts?
A device that changes electrical energy into mechanical energy.
What is an electric motor?
A permanent magnet is...
What is any magnet whose domain remains aligned?
A single wire wrapped into a cylindrical wire coil.
What is a solenoid?
The output in a step down transformer when the input is 80 volts.
What is 40 volts?
A thing that either lowers or heightens the voltage through primary and secondary coils.
What is a transformer?
if a magnet is broken into two is one a north pole and one a south pole
What is no? No matter how many pieces you break a magnet into each piece still has a north and south pole.
A device that uses an electromagnet to measure electric current.
What is a galvanometer?
In what everyday things do direct currents occur in.
What is a battery? (could be another answer if correct)
