The scope of eddy current testing is summarized in section 4.1. But with few exceptions the use of eddy currents is restricted to testing samples made either wholly or partly from metal and then only for regions at or just below the surface. However, the technique has the distinct advantage that no contact with the object under test is required and ...

SAE Technical Paper Series, 1956
<div class="htmlview paragraph">Even though friction brakes are very necessary, they have certain limitations as to heat capacity that is especially noticeable on hills, but is also a factor in congested fast moving traffic. A 45,000 lb tractor and semi will generate about 300 hp going down an 8% grade at about 45 mph and less than one third of ...

Abstract Eddy-current inspection is a nondestructive evaluation method based on the principles of electromagnetic induction. Eddy-current methods are used to identify or differentiate a wide variety of physical, structural, and metallurgical conditions in electrically conductive ferromagnetic and nonferromagnetic metals and metal parts ...

Eddy currents are induced in any conducting medium in which the magnetic field varies with time. Thus, eddy currents occur in the stator and rotor cores of electric motors and generators, in transformers, metallic recording heads (used in magnetic recording), and the like. These eddy currents can produce undesirable effects such as power loss, heating,
