Can you imagine turning something non-magnetic into something magnetic? Well, that is exactly what we did in 4 K. We turned an iron rod, a wire and battery into an ELECTROMAGNET. An electromagnet is a temporary magnet that allows you to control it. If you take a wire, wrap it around an iron rod and attach that in a complete circuit to a battery, you will make an electromagnet.
We wanted to see how the electromagnet would react when we wrapped the wire around the rod more and more times. The videos below will explain what we learned.
Our essential questions are:
1. How are electricity and magnetism related?
2. How can we make an electromagnets stronger?
3. How do you make a complete circuit?
