Eddy currents are curls of electrical current induced in conductors by a changing magnetic field. Eddy currents can be induced within conductors by a time-varying magnetic field which can be created by the circulation of some transient current in coil, electromagnet or transformer. The magnitude of...
Eddy currents induced in the cup by the spinning magnet create a torque that turns the needle against the force of a hairspring. Pretty simple — but how to put the instrument to work? [Glen]’s solution was to build what amounts to a variable frequency drive (VFD). His power supply ...
Eddy Current Definition: Eddy currents are loops of electric current induced within conductors by a changing magnetic field. Eddy Current Loss: In transformers, eddy currents cause energy loss as heat, which can be minimized by using laminated cores. ...

The present invention is an inspection instrument of the type which reacts to induced eddy currents in a workpiece to be inspected and includes a probe having at least a first probe coil. The instrument further includes a bridge circuit having the first probe coil connected in a first bridge ...
It is shown that magnetic field and eddy current calculations in axisymmetric systems can still be performed two-dimensionally if the axial symmetry is disturbed by small displacements perpendicular to the symmetry axis of the magnetic field source. Such a situation occurs for instance when the rotor...

In response, the test object generates eddy currents to oppose the alternating current in the coil. The eddy currents are then sensed by the same coil, separate coils, or magnetic field sensors. Changes in the induced eddy currents may be caused by changes to a material’s electromagnetic ...
Metallic particles, however, experience a lateral force due to the electric eddy currents induced in them as they move through the magnetic fields. Thus the metallic and the non-metallic particles can be collected in separate containers at the bottom of the ramp. The lateral deflection of a ...
]3 -Surface Currents field exists only between Sl and S2. F cannot penetrate S2, either. It must terminate on the right side of S2, but it cannot just magically disappear. According to Faraday's law, for the mmf to be zero in the center of S2, the enclosed current must be zero. ...
