| Keywords: Eddy currents due to magnet.svg eddy currents I <span style color red; >red</span> induced in conductive metal sheet C moving under a stationary magnet N showing the origin of the braking force The magnetic field lines B <span style color green; >green</span> from the North pole of the magnet extend down through the sheet The increasing field at the leading edge of the magnet left causes the currents to circle counterclockwise Thus from Lenz's law they create their own magnetic field directed up <span style color blue; >left blue arrow</span> which opposes the magnet's field thus exerting a drag effect on the magnet Similarly at the trailing edge of the magnet right the decreasing magnetic field induces eddy currents that circle clockwise This creates a magnetic field directed down <span style color blue; >right blue arrow</span> which attracts the magnet which also exerts a retarding force on the magnet 2014-07-22 12 16 52 own Chetvorno cc-zero Uploaded with UploadWizard Eddy current brakes Eddy currents | ||||
