a series circuit
What do the same poles of two magnets do?
repel
A material that allows electricity to flow through it easily is called ___?
a conductor
True or False - The flow of electricity can produce a magnet, and a magnet moving around or in a wire can produce electricity.
True
How are parallel and series circuits different?
A parallel circuit has multiple paths for electricity to travel and a series circuit has one path for electricity to travel.
parallel circuit
Where on a magnet is the magnetic field the strongest?
the poles
This uses a magnet to convert motion into electricity.
A generator
How are magnets and static electricity similar?
They can both attract and repel objects.
What does an electrical switch do?
It opens and closes a circuit.
