Young scholars visualize the magnetic field of a strong permanent magnet using a compass. The lesson begins with an analogy to the effect of the Earth's magnetic field on a compass. Students see the connection that the compass simply...

In this interactive tutorial students will explore magnetic force. Students will observe interactions of magnets and study magnetic fields. The source of magnetic properties is believed to be moving charge. Since moving charge produces...

In this activity, students take the age old concept of etch-a-sketch a step further. Using iron filings, students begin visualizing magnetic field lines. To do so, students use a compass to read the direction of the magnet's magnetic...

Students use a compass and a permanent magnet to trace the magnetic field lines produced by the magnet. By positioning the compass in enough spots around the magnet, the overall magnet field will be evident from the collection of arrows...

Captivating information about how frogs can levitate in magnetic fields. Easy to understand, it also explains how the Earth's magnetic field is produced.

The grand challenge for this legacy cycle unit is for students to design a way to help a recycler separate aluminum from steel scrap metal. In previous lessons, they have looked at how magnetism might be utilized. In this lesson plan,...

This lesson introduces students to the effects of magnetic fields in matter addressing permanent magnets, diamagnetism, paramagnetism, ferromagnetism, and magnetization. First students must compare the magnetic field of a solenoid to the...

In this science fair project, use Google Earth to determine if large mammals align themselves in respect to the earth's magnetic field. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

You can create a stronger, more concentrated magnetic field by taking wire and forming it into a coil called a solenoid. (Java tutorial)

Students explore the magnetic field surrounding a simple bar magnet. They can drag the compass around in the space surrounding the bar magnet, and observe the effect of the magnet on the compass needle.

Learn what magnetic fields are and how to calculate them with this reference page.

A handful of iron filings helps visualize the invisible magnetic field that circulates around a wire with a current running through it. (Java tutorial)

Whenever current travels through a conductor, a magnetic field is generated. (Java tutorial)

Experiment with the compass in this tutorial to see how it responds to magnetic fields.

Simulate the creation of an induced magnetic field through the use of a simple electric circuit. An interactive demonstration is included.

Students use a Magnetic Field Sensor to measure the magnetic field and the current in a solenoid. They explore factors that affect the magnetic field, study how the field varies in parts of the solenoid, and determine the permeability...

This site from NASA provides a short, illustrated description of the basics of magnetic fields and magnetic poles.

An electromagnetic simulation which replicates moving charged particles in two identical magnetic fields separated by a zero magnetic field gap.

This lab was designed to have students figure out the formula for the force on a charge moving through a magnetic field. Then they are to see how the direction of the force is dependent on the direction of the charge's motion and the...

This is a quantitative lab that will have students look at the direction of the magnetic field from moving charges in a wire. They can also get an intuitive sense of magnetic field strength factors based on the intensity of the circles...

Determine the mass and KE of a particle trapped in a magnetic field given the charge of the particle as well as the speed and strength of the field.

This lab was designed to have students test the factors that affect the path of charged particle in a magnetic field. Students will be able to adjust the mass and charge of the particle. They will be able to change the speed of the...
