Investigating Electricity and Magnetism
It's Electrifying!
We use electricity and magnetism every day, but how do they each work? How are they related?
There are two kinds of electricity: static electricity and electric currents. There are also two kinds of electric currents: direct (DC) and alternating (AC). Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow.
Opposites Attract
A + charge and a - charge will pull toward each other.
Similars Repel
Two - charges or two + charges will push away from each other.
Static Electricity

Electromagnetism
Electromagnetism is the interaction of these two important forces. Electricity and magnetism are very important and key to the workings of nearly every gadget, appliance, vehicle, and machine we use. Electromagnets are created by wrapping insulated wire around a nail and connecting both ends of the wire to the battery.
Electrical Energy
Electrical energy is from the flow of moving electrons. Electrons move through a path called a circuit. A circuit is a closed path along which an electric current travels. Electrical energy can produce other forms of energy such as thermal, sound, and light.
Circuits
Take a look at the four circuits to the right. Ever seen these in real life? Ask your parents, siblings, or friends if they've ever seen "open circuits" before! You'll be surprised at how often these are used in our every day lives!
For a fun, extra activity, try to find these circuits around your house and take a photo of them or write them down in a notebook! It will be a great topic to discuss later in the future.
Watch this super interesting video of Bill Nye the Science Guy demonstrating how electromagnets work!
In addition to the Bill Nye video, check this one out about circuits! It's very interesting to see some real ones in action.
