What is Magnetism?

It is just magnetic. This resource presents the concept of Earth's and another planet's magnetic field and how spacecrafts detect them. Learners study a problem using magnetometers and participate in three experiments to come up with a...

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,...

Investigate invisible forces. Young engineers design a setup that changes the direction of a steel ball using a magnetic force. The purpose of the setup is to model the gravitational pull of spacecraft by planetary bodies.

No GPS allowed! High school scientists continue to explore magnetic fields with a hands-on activity. After mapping the ambient magnetic field in the classroom and completing data analysis, they write about the similarities and...

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...

Your classes are sure to be attracted to the 32nd lesson in the exciting Crash Course physics series. Scholars learn the basics of magnetism and the forces created from current running through a wire. The lesson includes an application...

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,...

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor,...

Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...

Help your young scientists learn which materials are affected by magnetic fields with an activity that presents the information about different types of materials — diamagnetic, paramagnetic, and ferromagnetic — and their interaction...
