When a magnet is present, the particles of iron inside become slightly magnetized, so they attract each other and cluster into the lines that show the magnetic field patterns. The kit offers an interesting visual method of showing the power of magnetic fields.

This two piece set comprises of a rubberized foam ball representing the earth (with detailing of the continents and a strong magnet molded within it to create an invisible exterior magnetic field, similar to that of the earth) and a hand held magnet called a magnetic pole finder (which is a type of 3 dimensional compass). Place the magnetic pole finder near to the globe and it tilts and orientates itself to clearly show the strength, direction and position of the magnetic flux anywhere around the earth ball. This item truly is a magical way to see and understand the earth’s 3 dimensional magnetic field pattern. Comes with a teacher’s guide.
