conductors & insulator
This common metal is used inside most house wires because it is an excellent conductor
(what is copper)
Every magnet has these two opposite ends.
(What are North and South poles?)
This type of magnet can be turned on and off with a switch
(what is a Eletromagnet)
A path that is complete and allows electricity to flow is called this
(What is a Closed Circuit?)
This material is often wrapped around wires to keep us safe from electric shocks
(What is Rubber or Plastic?)
This happens when you try to push two "North" poles together
(what is repel)
To make an electromagnet stronger, you can add more of these to the metal core
(What are Coils/Loops of wire?)
this tool uses a tiny magnetized needle to point North south west and east
(What is a Compass?)
if you wanted to build a circuit, you would use this type of material to allow electricity to flow
(what is a conductor)
This is the invisible area around a magnet where it can pull or push objects.
(What is a Magnetic Field?)
This is the power source usually used in a classroom to create an electromagnet.
(What is a Battery?)
This type of electricity causes your hair to stand up after rubbing a balloon on your head.
(what is stactic electricity)
True or False: Distilled water is a better conductor than salt water
(what is false)
This is the only giant magnet that humans live on
(what is earth)
Unlike a permanent magnet, an electromagnet requires this to work
(What is an Electric Current?)
If one bulb goes out and they all go out, the lights are in this type of circuit
(What is a Series Circuit?)
These are materials that "resist" or block the flow of electricity
(what is insulators)
These three specific metals are naturally attracted to magnets.
(What are Iron, Nickel, and Cobalt?)
This device uses an electromagnet to turn electricity into motion (like in a fan).
(What is a Motor?)
This is a material that only conducts electricity under certain conditions.
(What is a Semiconductor?)
