500
Draw a closed circuit with a switch
(see teacher diagram)
500
The strength of this magnet depends on the number of loops in the wire and the amount of current in the wire
What is an electromagnet or a temporary magnet?
500
This is where bursts of energetic particles in solar wind collide with Earth's magnetic field which causes charged particles to be trapped in Earth's magnetic field to move toward Earth's poles

500
this is an electrical conductor that goes down the side of a house or building and into the ground.
