Explore the interactions between a compass and bar magnet. Discover how to use a battery and wire to make a magnet.

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...

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...

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 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...

In this classroom activity, the learners will investigate the magnetic pull of a bar magnet at varying distances with the use of paper clips. Students will hypothesize, conduct the experiment, collect the data, and draw conclusions that...

In this interactive unit students will see how magnets work and how they are used in some of the most useful and common devices today.

Students are introduced to a unique fluid--ferrofluids--the shape of which can be influenced by magnetic fields. This activity supplements traditional magnetism activities and offers comparisons between large-scale materials and...

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,...

In this physical science lab, students will investigate ways to control an electromagnet, how adding coils of wire can change the magnet, and the differences between an electromagnet and a bar magnet. Students will explain in their...

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

In this interactive tutorial students will explore how a magnetic field affects a current-carrying wire and also how two current-carrying wires affect each other. They will learn about Biot-Savart, Ampere's Law and the magnetic field...

The New York Times Learning Network has developed interactive & printable crossword puzzles. The theme of this puzzle is magnetism and electricity. Requires Java.

Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through...

Students begin working on the grand challenge of the unit by thinking about the nature of metals and quick, cost-effective means of separating different metals, especially steel. They arrive at the idea, with the help of input from...

HyperPhysics is an exploration environment for concepts in physics by Georgia State University which employs concept maps and other linking strategies to facilitate smooth navigation. This section focuses on electricity and magnetism.

In this fun lab activity, students will learn about the attraction and repulsion of magnets. Students will discover that like poles repel while unlike poles attract.

Our magnets are like world-class athletes - Team Tesla, if you will. They have an awful lot of power, but to stay in that kind of shape, they need to eat and drink - a lot.

The purpose, life, and hazards of the Earth's magnetic field are discussed as they relate to magnetic storms. This includes their impact on animals, auroras, and even compasses. Interactive features are also included in this...
