This unit launches with a slow-motion video of a speaker as it plays music. In the previous unit, students developed a model of sound. This unit allows students to investigate the cause of a speaker's vibration in addition to the effect.

This is the fifth version of a free textbook on paleomagnetism, published in 2018. The material is advanced but does provide information on many different topics for students doing research. Chapters include problems for students to...

This site from Integrated Publishing provides three different examples of theories of magnetism.

Students learn the relationship between the electric and magnetic fields. Specifically, they verify that a magnetic field is created in a current carrying coil of wire and a changing magnetic field can induce a current in another coil of...

This lab is designed to have students look at the deflection of a cathode ray beam using magnetic fields and electric fields.

An electromagnetic induction model that simulates an electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter.

Help students learn how scientists use powerful tools to visualize, study and control materials at the nanoscale.

Teacher directed activity shows students how flowing electrical current produces a magnetic field by building a simple motor.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

This article helps explain the concept of electromagnetism as well as magnetic fields and the properties of the speed of light.

In this activity, students will create their own simple compass, be able to explain how a compass works, understand that the Earth's magnetic field has both horizontal and vertical components, and learn more about cardinal directions.

Scientists continue to learn from their observations long after the largest collision in history was recorded. Was Comet SL-9 actually an asteroid? What were the dark impact clouds made of? What were the effects on Jupiter's magnetic field?

Learn the convention for describing the direction of magnetic fields. Challenge questions are included.

Theoretical physicist Julian Schwinger used the mathematical process of renormalization to rid the quantum field theory developed by Paul Dirac of serious incongruities with experimental observations that had nearly prompted the...

At the dawn of the computer age, magnetic core memory helped make data storage possible, and showed surprising staying power in a field where components are constantly being replaced by new and improved products.

Gerd Binnig co-developed the scanning tunneling microscope (STM) with Heinrich Rohrer. The STM allowed scientists entry into the atomic world in a new way and was a major advance in the field of nanotechnology. For their achievement,...

Humphry Davy was a pioneer in the field of electrochemistry who used electrolysis to isolate many elements from the compounds in which they occur naturally. Electrolysis is the process by which an electrolyte is altered or decomposed via...

Born in Palo Alto, California, and raised in Cambridge, Massachusetts - homes to Stanford and the Massachusetts Institute of Technology, respectively - you could say Eric Cornell was destined to become a renowned scientist. And while he...

Luigi Galvani was a pioneer in the field of electrophysiology, the branch of science concerned with electrical phenomena in the body. His experiments with dissected frogs and electrical charges led him to suggest the existence of a...

Heike Kamerlingh Onnes was a Dutch physicist who first observed the phenomenon of superconductivity while carrying out pioneering work in the field of cryogenics. An important step on the way to this discovery was his success in...

Provides a short explanation of the similarities between magnetism and electricity, the properties of their fields, and the effect they each have on a charged particle.

Site from NASA contains a collection of 91 questions pertaining to the Earth's atmosphere, magnetic field, ionosphere, rotation and origin of life.

Can you think of an experiment that would let you see how magnetic force depends on distance?

In this experiment, students experience the Curie point--and what happens when a piece of iron gets too hot to attract a magnet.
