Audience: High school
Materials Cost: Over $20 per group of students

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic... (View More)

This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple... (View More)

This is an activity about electromagnetism. Learners will use a simple circuit powered by a battery source to investigate the strength of the magnetic field produced by a coil of wire in the circuit. The strength will be indicated by the deflection... (View More)

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

This lesson is an introduction to the use of a magnetic compass. At a specific location, learners will locate an object using a compass, identify its bearing, and others will attempt to locate the object by only knowing the bearing reading and the... (View More)

This is an activity about the Kp index, a quantification of fluctuations in the Earth's magnetic field due to the relative strength of a magnetic storm. Learners will take a reading from a magnetometer site and make a Kp index estimate to predict... (View More)
