3-D Magnetic Field
In this magnetism learning exercise, students build a 3 dimensional magnetic field by using a juice bottle, a test tube, iron fillings and a magnet. Students write a descriptive story about what they observe once their bottle is complete...
Teach Engineering
Magnetic Fields
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 associated...
Teach Engineering
Electricity and Magnetic Fields
Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.
