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...

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.

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...

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.

From ABC News in Science, this article, "Sun's magnetic field twisted and tangled," discusses images taken of "plumes of gas" which are rising from the sun's corona.

This Beth Israel Deaconess Medical Center site offers a comprehensive look at MRI exam phases, preparation, technology, equipment, safety, and research. Images and labeled diagrams are also provided on this site.

In this fun, engaging activity, students are introduced to a unique type of fluid--ferrofluids--whose shape can be influenced by magnetic fields! Students act as materials engineers and create their own ferrofluids. They are challenged...

In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn...

This site describes and demonstrates a number of important concepts related to direct current circuits. Information on many of the featured topics, such as the use of Ohm's law and Kirchhoff's laws. Examples of featured topics include...

This instructional activity introduces the MRI Safety Grand Challenge question. Young scholars are asked to write journal responses to the question and brainstorm what information they will need to answer the question. The ideas are...

This lesson ties the preceding lessons together and brings students back to the grand challenge question on MRI safety. During this lesson, students focus on the logistics of magnetic resonance imaging as well as the MRI hardware....

In this instructional activity learners learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as...

In this interactive tutorial students will look at the energy stored in the magnetic field of an inductor. Self-inductance and mutual inductance will be distinguished and circuits with capacitors and inductors, or LC circuits will be...

In this activity, Students can use a Magnetic Field Sensor to measure the magnetic field of the Earth and to determine magnetic north. They will also calculate the magnetic inclination and declination at their location.

This lab was designed to have students look at the graphs for flux vs. time and electromotive force vs. time for a coil spinning in a magnetic field. Students will be able to vary the size of the coil, the rate at which the coil spins...

This is a five-question quiz related to the passage "The Effect of Contrast Agents on MRI Signals."

A slideshow and a short multiple-choice quiz on the basic concepts and vocabulary of magnetism.

Hands-on project where the learner constructs a magnetometer to monitor and measure changes in earth's magnetic field. These changes can then be used to track solar storms.
