Magnetism and Earth's Magnetic Field by Wendy Esch

Project:     NASA Heliophysics Teacher-Developed Lessons

Students will investigate magnetism and electromagnetism using a smartphone magnetometer. Students will be given materials to make a simple motor, then they will generate electricity by playing jump rope outside, and use a compass to locate objects when they are given a compass heading. They will also examine the problem with using a compass during a geomagnetic storm. All of the material examined up to this point will be applied to the study of Earth’s magnetic field. Lastly, students will use their smartphones to calculate the strength of the magnetic field at their location and potentially determine the existence of a geomagnetic storm.
