Mapping a Dipole Magnetic Field

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...

Magnets don't grow in fields, but magnetic fields are important to understand. The lesson covers the effect electricity has on magnetic fields. Scholars use a compass, magnets, and electrical wire to test magnetic fields and energy...

So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...

High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.

Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values...

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,...

Give credit where credit is due—thank Ampere any time you use an electric motor! The 33rd installment in the Crash Course physics series explains how Ampere's Law applies to a long, straight wire. The discussion then expands to the...

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.

Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.
