Mapping a Dipole Magnetic Field

Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

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...

Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...

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,...

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...

In this interactive tutorial students will explore magnetic force. Students will observe interactions of magnets and study magnetic fields. The source of magnetic properties is believed to be moving charge. Since moving charge produces...

Introduce your class to magnetic fields with an activity that demonstrates that a compass is affected by the magnetic field of the earth, unless a closer, stronger magnetic field is present. Pupils can use this fact in the...

Physical or earth science pupils prepare a magnetometer by inducing magnetism into a pair of straight pins. As the pins hang from a thread, they can be used to detect the magnetic field or poles of a magnet. They could also be used as a...

Students explore how compass and Gauss meter detect a magnetic field. In this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.
