In this activity about magnetic fields and their relation to the Sun, learners will simulate sunspots by using iron filings to show magnetic fields around a bar or cow magnet, and draw the magnetic field surrounding two dipole magnets, both in... (View More)

This is an activity about the basic properties of magnets and magnetism. Learners explore concepts such as magnetic fields and polarity, which form the basic ingredients of a study of Earth's magnetic field and the technology of magnetometers.... (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)

Keywords: Magnetism; Lenz's Law
Audience: High school
Materials Cost: $1 - $5 per group of students

This is an activity about the properties of electromagnets, which is a crucial underpinning for understanding how magnetic fields are generated in nature, in the surface of the Sun, and in the interior of Earth. Learners will create an electromagnet... (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)

In this activity, students will demonstrate the generator effect, which is due to electromagnetic induction when a conductor (a long metal wire) moves through a magnetic field. Materials required to this activity include: a 100-foot extension cord... (View More)

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

This is an activity about the movement, or "wandering," of our Earth's magnetic poles. The learner will explore this concept by measuring and calculating the distance the Earth's north magnetic pole has moved over the past 400 years and calculating... (View More)

Audience: Middle school, High school
Materials Cost: Free

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 is an activity about electromagnetism. Learners will use a compass to map the magnetic field lines surrounding a coil of wire that is connected to a battery. This activity requires a large coil or spool of wire, a source of electricity such as... (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)
