like poles
these poles attract
names of the poles of a magnet
an object a magnet will pick up
a plastic comb is this
the bulb will stay lit if this kind of object is added to the circuit
used as the core of an electromagnet
A magnets pull or attraction is strongest here
changes electricity into light energy
Best material for the core of an electromagnet
an example of electrical energy into sound energy
a flashlight turns electrical energy into what
a iron nail is this
an oven turns electrical energy into what
open and closes a circuit
True or False: The neatness of the coils affect the strength of the electromagnet
these poles repel
stops the flow of electricity
allows electricity to flow through it
all other bulbs will stay lit if one goes out
A stronger battery will make an electromagnet stronger or weaker
an example of electrical energy into heat energy
The type of circuit you have to have to make a light bulb light up
three factors that affect the strength of an electromagnet
has more than one path for the electricity to travel on
three types of energy that can be transformed from electrical energy
