The Magnetic Sun

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

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...

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...

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...

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. 

Something big is happening on the sun. The sun's global magnetic field is about to flip, a sign that Solar Max has arrived. (August. 5, 2013) [4:03]

Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

Sunspots, solar flares, coronal mass ejections ... why is the sun so stirred up? Scholars watch animations of the interaction between moving plasma and magnetic fields and discuss the sun's behavior. The activity, part of NOVA's sun...

Captivating information about how frogs can levitate in magnetic fields. Easy to understand, it also explains how the Earth's magnetic field is produced.

Students visualize the magnetic field of a strong permanent magnet using a compass. The lesson begins with an analogy to the effect of the Earth's magnetic field on a compass. Students see the connection that the compass simply responds...
