repel, attract
Closed Circuit
Static electricity
Objects that electricity does NOT flow through easily are called this
Insulators
iron, nickel, or cobalt
A circuit where electricity is not flowing
Open circuit
The two poles in a bar magnet
North and South
Electricity that occurs in nature is called this.
Static electricity
The area around a magnet that attracts objects. It is strongest at the poles
Magnetic field
A circuit where electricity has exactly ONE path to follow. If any part of the circuit is not working, it will not work.
Series circuit
Name two examples of conductors
Humans, water, metals, etc.
Electricity that is man-made is called this. It must flow to function.
Current electricity
True or false. Bar magnets are permanent, but electromagnets are temporary.
True
A circuit where there are multiple paths for electricity to flow. If one part does not work, electricity can still flow.
Parallel circuit
Name two examples of insulators
Wood, plastic, rubber, etc.
Name a difference between static electricity and current electricity
Static electricity is a sudden, quick movement of electrons. Current electricity flows along a circuit.
Static electricity occurs in nature. Current electricity is man-made.
Name a difference between bar magnets and electromagnets
Electromagnets are man-made, bar magnets found in nature.
Electromagnets can be turned on and off, bar magnets can not.
Strength of electromagnet can be increased, bar magnet can not.
The three parts needed for a circuit
Power source, wire, load
A switch
