- What is the primary characteristic of an eddy current in a conductor exposed to a changing magnetic field? A) Eddy currents flow in closed loops within the conductor and can cause energy loss in the form of heat. B) Eddy currents produce a magnetic field that opposes the applied external magnetic field. C) Eddy currents are negligible in conductive materials with high magnetic permeability. D) Eddy currents are directly proportional to the resistivity of the material.Lines of flux is the magnetic field in the form of concentric circles around the conductor true / falseThe emf induced in a conductor when placed in magnetic field can be determined by the Lenz's law True False
