Source Institutions
Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.
Magnet Powered Pinwheel
Source Institutions
Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.
Exploring Magnetic Field Lines
Source Institutions
In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.
Curie Point
Source Institutions
In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.
Magnetic Pendulums
Source Institutions
In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.
