Magnets
the name of the opposite sides of a magnet
poles
The relationship between electricity and magnetism is known as this
electromagnetism
A type of electric current that changes direction
alternating current
this is the name of an object that, among other things, attracts iron and materials containing iron
magnet
The area of magnetic force around a magnet
magnetic field
if electricity is flowing through a conductor, that flow would be called this
current
The type of current created by a battery
direct current
A loop of wire with an electric current running through it that behaves like a magnet
solenoid
These flakes of metal can be used to map a magnetic field
iron filings
a device used to raise voltage
step up transformer
This is the type of current used in a transformer
alternating current
If you add a core of iron to a solenoid, you have made this
electromagnet
This is a tool used to determine direction based on the earth's magnetic field
compass
the subatomic particle that flows in an electric current generated by a power plant
electron
the use of a magnetic field to generate an electric current
induction
This is a device that converts electrical energy into mechanical energy, to power a fan, for example
electric motor
something that has a strong, rather than weak or nonexistent, attraction to a magnet would be best described as this
ferromagnetic
the pressure that pushes electricity
voltage
A loop of a conductor which must be closed in order for an electric current to be conducted
circuit
This is a device used to measure electric currents
