Standard 28: Accurately compares and contrasts the properties and behaviors of magnetism and electricity

It's all about electrons.

Electricity and magnetism, while different processes, are inseparable. Their similarities are almost too many to count. First, they both subscribe to the law of "opposites attract, like repel". Electricity has positives and negatives just like magnetism, although in magnetism they're called north and south. Another similarity is that distance matters for both of them. The push or pull of the positives and negatives is going to be stronger depending on how close the two bodies are. Their interaction with metal is comparable, and both have the ability to transfer their attractions to metals.

Some of their differences are that first, magnetism has a physical push or pull that we can observe with our own muscles. Electricity is only observable through completed circuits. Electricity is also easy to transfer into thermal energy, while magnets will generally not heat things up.
