摘要： Inductor of eddy currents for magnetic tape testing comprises of a nonferromagnetic dielectric supporting element (1) having a longitudinal groove in the operational butt end, an exciting conductor (2) shaped as wire segment and placed within said groove of said supporting element (1), and a suitable means (3) for connection of said conductor (2) to a source (4) of pulse current. Scanner for magnetic tape testing comprises of a rigid body (9); aforesaid inductor of eddy currents as such and the source (4) of pulse current, which are mounted on said body (9). These closely coupled devices have heightened sensitivity to the surface defects in electroconductive (especially nonferromagnetic) articles and secure high resolving capacity of magnetic tape testing.
