Building an Electromagnet
Your pupils can build their own electromagnet — awesome! The culminating activity in an eight-part series challenges groups to design and build their own electromagnet. The goal of the activity is to build a magnet capable of picking up...
Teach Engineering
Circuits and Magnetic Fields
Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is created...
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.
