This two piece set comprises of a rubberised ball representing the Earth (with detailing of the continents and a strong magnet moulded within it to create an invisible exterior magnetic field, similar to that of the Earth) and a hand held magnet called a Magnetic Field Finder (which is a type of 3 dimensional compass).
Place the Magnetic Field 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. The Magnetic Field Finder is also useful to reveal the 3 dimensional nature of magnetic fields around any Magnet and is a real step up from iron filings sprinkled onto a piece of paper. A really magical way to see and understand the Earth’s 3 dimensional Magnetic Field Pattern.
Specification: Size of globe: 110mm dia.
