A wonderfully rich presentation teaches about magnets and magnetism. Each slide is packed with interesting information on the discovery, history, physics, and uses for magnets. Good photographs, and an emphasis on vocabulary are part of...

The biggest magnet in the world is at the Los Alamos National Laboratory in New Mexico and can reach 100 tesla. By comparison, magnets that lift cars are about two tesla. The 11th presentation in this series covers magnetism,...

Six simple images pull your class into magnets. Most of the pictures show magnetic fields as revealed by iron filings. Concepts are explained in print along the bottom of each slide and include magnetic force, force fields, poles,...

If you are looking for a concise set of slides dealing with the basics of magnetism, look no further. Each slide defines a different magnetism concept: poles, fields, atoms, currents, electromagnets, motors, and generators. The only...

All phenomena concerning magnets, their field lines and impact on objects are covered. The trivia surrounding field lines and the earth, electric charges, repulsion and attraction is plentiful. The slide show continues after twenty...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

Ask your class what they know about magnets, then take some time and explain basic magnetic properties. This presentation covers polarity, magnets in compasses, and magnetic force. It provides a quick hands-on exploration where kids...

Attract your class to magnetism with this straightforward presentation. Using bullet points and simple phrases, viewers are taught the basics of magnetism. There are no pictures or diagrams to help explain, so you might want to add a few...

Provide physical science explorers an overview of magnetism with this collection of slides. The third slide posts hyperlinks to websites that cover magnetic fields in detail, so ideally this presentation would be viewed by small groups...

Every knows that opposites attract! Here's a presentation that uses this background knowledge to explain magnetic fields and forces. The resource also explains the shape of magnetic fields and how to determine the direction of forces.

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

This lesson will introduce what a magnet is and how magnets work.
