21. The skin effect also increases inductance by inducing eddy currents in the central plasma. 22. The saturation probes contain conventional eddy current coils and magnets. 23. Metals are extracted using magnetic separators, air flotation separator columns, shaker tables or eddy currents . 24. It is believed that they form in eddy currents . 25. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.26. Additionally, mechanisms for reducing eddy currents are sometimes implemented. 27. The eddy currents flowing through the resistance of the material heat it by Joule heating. 28. French physicist L�on Foucault ( 1819 1868 ) is credited with having discovered eddy currents . 29. This will be usually situated on an east / west axis to prevent eddy currents . 30. Thus an eddy current brake has no holding force.
