Magnetism

Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams....

Working under specific constraints and with designated criteria, groups work together to create a product using an assembly line process. In addition, they work through the entire engineering design process with an excellent graphic to...

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...

Oxygen has many important properties ... such as sustaining most living things. But magnetism? Discover the behavior of oxygen in its chilly liquid form using a video from a larger playlist on physics. Watch as liquid oxygen is poured on...

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil. 

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, learners...

The earth has a giant magnetic field caused by the liquid iron that constantly moves in the outer core. Scholars explore the magnetic fields of four different planets. The strength and alignment of the poles relates to the implications...

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...

Our atmosphere is pretty amazing! How does it minimize the effects of solar weather? Scholars discover Earth's first line of defense against the sun—the magnetosphere. The activity, one of several in a sun unit from NOVA, explains how...
