The ends of a magnet are called the
poles
A temporary magnet formed when electric current flows through a wire coiled around certain metal cores
electromagnet
List two ways magnets can be used to produce electricity
by moving a magnet through a coil of wire
by moving a coil of wire through a magnetic field
Are magnetism and electricity related?
Yes
Asher's family is building a new home. Will it be better to have the outlets and lights wired in a parallel circuit or a series circuit? Why?
A parallel circuit because it would allow the outlets and lights to be turned off and on individually.
Name two things that use electromagnets.
fire alarms
hair dryers
microwave ovens
computers
doorbells
cranes
maglev trains
The pushing or pulling force caused by a manet is called
magnetism
an unbroken path which negative charges can flow is called a
circuit
produces electricity by using a coil of wire and a magnet
generator
The pushing or pulling of a force caused by a magnet is called
magnetism
What are the two kinds of charges that particles of matter can have?
negative
positive
a material that does not allow electricity to flow through it easily
insulator
A magnet's magnetism is strongest at the
magnet's poles
An object that attracts certain metals is called
a magnet
The area around a magnet where the force of the magnet can act is called the
magnetic field
What two things does every circuit have?
an unbroken path
a power source
A magnetic field is caused by a _____________ flowing through a circuit.
current
What is all matter made up of?
small particles with an electric charge
Objects with the same kind of charge push away from, or ________________ each other.
repel
The continuous flow of negative charges through a material is called ______________ ______________
current electricity
A material that allows electricity to flow through it easily
conductor
A form of energy that involves the flow of electrical charges is called
electricity
When electrical charges build up on the surface of an object, ____________ occurs.
