This article surveys inductance and its different forms. It discusses numerous topics associated with inductance such as Faraday's Law, self and mutual inductance, inductors, and magnetic field lines.

This short module covers permanent magnets, the concept of polarity, and the manufacture of permanent magnets. Includes some quiz questions.

Gives a simple description of the theory of magnetism and the properties of a magnet. Very good descriptions for beginning level.

In this lesson, students determine which objects are helpful in determining the location and position of magnets that are hidden inside of closed boxes.

This article discusses a map generated by the European Space Agency's Swarm mission that depicts Earth's magnetic field using satellites to measure magnetism. The map reveals magnetic stripes and magnetic anomalies. The article includes...

Physicists use a hand mnemonic known as the right-hand rule to help remember the direction of magnetic forces. The right-hand rule is based on the underlying physics that relates magnetic fields and the forces that they exert on moving...

[Free Registration/Login may be required to access all resource tools.] Explains how Earth is a magnet, its geographic and magnetic poles, and its magnetic field.

A current can be induced in a conducting loop if it is exposed to a changing magnetic field. (Java tutorial)

Anders Celsius is most familiar as the inventor of the temperature scale that bears his name. The Swedish astronomer, however, also is notable as the first person to make a connection between the radiant atmospheric phenomenon known as...

Explore and review magnetism in this review guide.

Named in honor of Danish physicist Hans Christian Oersted, Denmark's first satellite has been observing and mapping the magnetic field of the Earth.

In this activity, students use an old fashion children's toy, a metal slinky, to mimic and understand the magnetic field generated in an MRI machine. The metal slinky mimics the magnetic field of a solenoid, which forms the basis for the...

This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI....

The lesson begins with a demonstration introducing students to the force between two current carrying loops, comparing the attraction and repulsion between the loops to that between two magnets. After formal lecture on Ampere's law,...

This set of activities has students using everyday items (batteries, magnets, compasses, iron and paper clips) to reveal the connection between electricity and magnetism. Ideally, students will already have experience building simple...

An interactive simulation that teaches about Faraday's Law, magnets, and magnetic fields by showing how a change in the magnetic flux can produce a flow of electricity. This simulation can either be downloaded or played online and...

This is a sample lesson on electromagnetism. It includes animated diagrams, interactive exercises, an audio option for reading the text, and comprehension questions throughout where students can type their answers or pick from...

Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer.

The human body has an impressive ability to heal itself after injury, but humans have nothing on planaria. Planaria have an amazing ability to regenerate. An entire animal can regenerate from just a fraction of the body. This project...

An article defining what magnetic force is and how to calculate it.

In MRI, magnetic fields and radio wave pulses combine to get a unique, and medically beneficial, response from your body's hydrogen atoms. Take a peek in this tutorial.

Chemist Paul Lauterbur pioneered the use of nuclear magnetic resonance (NMR) for medical imaging. He developed a technique, now known as magnetic resonance imaging (MRI), in the early 1970s that involves the introduction of gradients in...

Although he is best known as one of the greatest mathematicians of all time, Carl Friedrich Gauss was also a pioneer in the study of magnetism and electricity. To facilitate an extensive survey of terrestrial magnetism, he invented an...

See how electricity and magnetism interact with this activity. Activity has students creating a current by swinging a copper coil through a magnetic field. The copper coil will start a second coil swinging as well.
