An object that attracts certain materials, usually objects made of iron or steel
What is a MAGNET
100
The only kind of charges that can move
What is NEGATIVE CHARGES
100
A material that current can pass through easily
What is a CONDUCTOR
100
An electromagnet needs this to work
What is ELECTRIC CURRENT (ELECTRICITY)
200
A temporary magnet
What is an ELECTROMAGNET
200
The charge that stays on an object
What is STATIC ELECTRICITY
200
This is what happens when you walk around and rub your feet on carpet
What is NEGATIVE CHARGES FROM CARPET MOVE ONTO YOUR BODY
200
The item that was our conductor during our investigations
What is COPPER WIRE
200
The strongest parts of a magnet
What are MAGNETIC POLES (POLES, NORTH-SEEKING POLE, SOUTH-SEEKING POLE, NORTH & SOUTH POLES)
300
The space where electric forces occur around an object
What is an ELECTRIC FIELD
300
The space around a magnet where the force of the magnet can act
What is a MAGNETIC FIELD
300
This happens when two positively charged balloons are placed near each other
What is REPEL (separate, move apart)
300
If the path is broken anywhere in one of these light bulb(s) will not light
What is a SERIES CIRCUIT
300
This is how to get two magnets to repel each other
What is PLACE TWO NORTH(-SEEKING) POLES TOGETHER OR TWO SOUTH(-SEEKING) POLES TOGETHER
400
The measure of extra positive or negative particles an object has
What is CHARGE
400
A path made for an electric current
What is a CIRCUIT
400
This happens when one positively charged balloon and one negatively charged balloon are placed near each other
What is ATTRACT (come together)
400
If one path is broken in one of these the light bulb in the other path can still light
What is a PARALLEL CIRCUIT
400
How bar magnets and electromagnets different?
Electromagnets are temporary, need electric current, and be switched on and off, while bar magnets are permanent, do not need electric current to work, and cannot be turned on or off.
500
Material that current cannot pass through easily
What is an INSULATOR
500
A material that slows down but does not stop the flow of current
What is a RESISTOR
500
Matter in an object normally has this kind of charge
What is NEUTRAL CHARGE or EQUAL POSITIVE AND NEGATIVE PARTICLES
500
This was the resistor in our first investigation
What is the TINY COIL OF METAL INSIDE LIGHT BULB
500
How can you make an electromagnet stronger?
You can coil the wire, coil even more wire around already coiled wire, increase the amount of current (ex: using more batteries)
