Magnetism
This is the force that makes magnets stick together or push apart
magnetism
This is the unit used to measure electric current.
ampere
What is the field of electromagnetic
A magnet has these two ends.
north pole and south pole
This material is a good conductor of electricity and is used in wires.
copper
What material is commonly used for electromagnet
Iron
This is the invisible area around a magnet where it can attract or repel objects.
magnetic field
What object stores electricity used for electronic devices
What are the two charges in electricity
Negative and positive
When you bring two magnets with the same poles together, they do this.
repel
This material, like rubber or plastic, prevents the flow of electric current.
insulator
Which part of an atom has a negative charge and moves to create electric current?
Electron
This is what happens when two magnets with opposite poles are brought together.
attract
This is a measure of how difficult it is for electric current to flow through a material.
Resistance
who discovered electricity and magnetism
Michael Faraday
