This is the name for a material that does not allow electrons to flow through it easily, like rubber or glass.
insulator
An electric current is specifically defined as the flow of these subatomic particles through a wire.
electrons
These are the two ends of a magnet where the magnetic force is the strongest.
poles
This is the distance between one crest of a wave and the next.
wavelength
These are the only waves on the EM spectrum that the human eye can see.
visible light
When you rub a balloon on your hair, this specific subatomic particle is transferred to create a charge
electrons
For electricity to flow, the circuit must be this—meaning there are no breaks in the path.
closed circuit
You can create this temporary magnet by wrapping a wire around an iron core and running a current through it.
electromagnet
Sound is this type of wave, which requires a medium (like air or water) to travel through.
mechanical
These waves have the longest wavelength and are used to carry signals to your TV and cell phone.
radio waves
This law states that "like charges repel, and opposite charges..."
attract
If you want to increase the amount of electric current flowing through a wire, you would need to increase this "pushing" force.
voltage
This is the invisible area around a magnet where magnetic forces can be felt.
magnetic field
Humans perceive the frequency of a sound wave as this.
pitch
Color that is made when ALL visible light is absorbed
Black
If a neutral glass rod is rubbed with silk and loses electrons, the rod now has this type of net charge.
positive
This component of a circuit is used to slow down the flow of electrons to ensure other parts don't get too much power.
resistance
If you have two magnets and you bring two North poles together, they will do this.
repel
Sound travels fastest through this state of matter because the molecules are packed tightly together.
solid
Color that is made when ALL visible light is reflected
White
Lightning is a giant, dramatic example of this process, where a built-up charge suddenly moves to find balance.
static discharge
If a wire is disconnected or a switch is turned off, the loop is broken and becomes this type of circuit.
open circuit
To make an electromagnet stronger, you can either increase the number of coils in the wire or increase this "push" from the battery.
voltage or current
This is the part of a longitudinal wave where the particles are spread far apart.
rarefaction
These high-energy waves are used in hospitals to see through skin and muscle to check for broken bones.
