Magnetic Field Activities for the High School Classroom
This unit is designed to acquaint the student with the magnetic field. The assumed average student has some familiarity with the uniform gravitational field of classical Newtonian dynamics and kinematics lessons. This is not required however. The unit is meant to introduce the idea of a field through investigations of magnetic fields as produced by various common magnetic materials and direct currents.
The fastest coronal mass ejection was recorded on August 4, 1972 and traveled from the sun to earth in 14.6 hours - a speed of nearly 10 million kilometers per hour!
