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

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

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...

Work samples, phenomena, assessment templates, and videos that directly address standard: MS-PS2-5: electric, magnetic, and gravitational fields.

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...

Students will build a simple version of a magnetometer and use it to discover the types of areas of the Sun that have very strong magnetic fields. Students will then describe what the types of features associated with the Sun's strongest...

[Free Registration/Login may be required to access all resource tools.] Discusses what a magnetic field reversal is and the evidence that this has happened with the Earth.

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 comprehensive study guide covers the main terms and concepts needed for an earth science unit on the earth's shape and magnetic field. Review questions are included at the bottom of the study guide.

Get information about rotating magnetic fields and how electric machines use them for their operation. Discusses synchronous speed and number of poles on an electrical machine. The accompanying article discusses the topics found in the...

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 students 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...

Here is the site to help you learn all about magnetism and magnets! Find out what a magnet is and how it works. Click for additional details on charges, conductors, magnetic fields, currents, resistance as well as the Laws of Faraday and...

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

When a magnetic field is applied perpendicular to the flow of current, the field causes resistance in the current. This is the Lorentz force at work, and can be observed well in the Hall effect. (Java tutorial)

Move a bar magnet or an electromagnet around to see how the magnetic fields change. Requires Java.
