Hidden Magnetic Fields
A magnetic field is a space around a magnet that the force of magnetism acts. It’s surprising how strong the forces are the closer you are to the magnet. This is a quick and simple experiment to investigate and discover magnetic field strength. Do you think four magnets have a stronger magnetic pull than one?
You’ll find the answer quite surprising… which is: it depends.
- stack of round magnets (7-9)
- film canisters (or small containers like M&M containers)
- clay or foam or tissue
