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...

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,...

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...

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.

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 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...

Find the force and the direction of the force on a charged particle moving through a magnetic field.

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...

A bar magnet model built by placing a group of magnetic dipoles along the magnet. This simulation shows the magnetic field of a bar magnet, and has a movable compass which shows the magnetic field values.

In this activity, students use the same method as in the activity from lesson 2 to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced...

[Free Registration/Login may be required to access all resource tools.] The Earth's magnetic field and how it protects life on Earth, and how it is used for navigation.

Learners investigate current-carrying wires in magnetic fields. Some topics explored in the activities are forces, magnetic dipoles, and circuits. The resource consists of video clips, lecture notes, exam questions, java applets, and...

College-level physics course highlighting electricity and magnetism. This course is divided into several modules including electric fields, magnetic fields, electromagnetic forces, conductors and dielectrics, electromagnetic waves, and...

A well illustrated activity where students investigate and draw the magnetic field lines created with a bar magnet and a compass.

This lesson discusses the result of a charge being subject to both electric and magnetic fields at the same time. It covers the Hall effect, velocity selector, and the charge to mass ratio. Given several sample problems, students learn...

This lesson begins with an activity in which young scholars induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large...

This lesson begins with a demonstration of the deflection of an electron beam. Young scholars then review their knowledge of the cross product and the right hand rule with sample problems. After which, students study the magnetic force...
