Teach Engineering: Circuits and Magnetic Fields
In this activity, students use the same method as in the activity from lesson 2 to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced...

Teach Engineering: Drawing Magnetic Fields
Students use a compass and a permanent magnet to trace the magnetic field lines produced by the magnet. By positioning the compass in enough spots around the magnet, the overall magnet field will be evident from the collection of arrows...

Khan Academy: Electrical Engineering: Electrostatics
Electrostatics is the study of forces between charges, as described by Coulomb's Law. We develop the concept of an electric field surrounding charges. We work through examples of the electric field near a line, and near a plane, and...
