11. A metal detector might detect eddy currents in even a wire without current. 12. Linear encoder technologies include optical, magnetic, inductive, capacitive and eddy current . 13. This eddy current is formed by the movement of the wheels. 14. The varying magnetic field induces eddy currents on the metal surface. 15. The eddy current technique is compact, lightweight and powerful, but inefficient. 16. This was caused by a temporary electric current, or eddy current , in the electromagnet. 17. (If the changes are cyclic there will be losses for hysteresis and eddy currents . 18. The laminations are to reduce hysteresis and eddy current losses. 19. Eddy currents are electric currents that occur in conductors exposed to changing magnetic fields.20. The alternating magnetic field induces eddy currents in the plates.
