Eddy Currents & Magnetic Fields

Explore the invisible fields of force around magnets. Iron Filings are great to experiment with magnetic fields. With Sealed Iron Filings, see how iron filings react with magnets and show magnetic fields without the mess. You can use the Magnetic Field Viewer Card to see the poles of a magnet. Eddy Current Rods and Eddy Current Tubes are great for demonstrating Lenz's Law!
