Levitation with arbitrary motion Here is an example of an aluminum plate that is 3 mm thick and positioned above two coils whose current is 180 degrees out of phase. The motion of the plate when the initial position is off center can be modeled using three degrees of freedom: translation along the x and y-axes and rotation about the z-axis.

Perforated Levitating Disk This page examines a disc that first jumps from its resting position, oscillates for a certain period until finally levitating at a specific height above a coil, which is using an AC current as its input source. Of the two animations that accompany this page, one shows the dynamic position of the levitating plate whilst the other demonstrates the current density of the plate through a few cycles.

TEAM problem 15 - A Problem in Nondestructive Evaluation TEAM Problem 15 looks at the inversion of eddy-current data and the reconstruction of flaws in electromagnetic nondestructive evaluation (NDE). The model used is one of a circular coil moving along an aluminum plate that contains a slot. This gallery page demonstrates how MagNet can be used to calculate the resistance and inductance of the driving coil at various positions.

TEAM problem 27 - Eddy Current NDT and Deep Flaws The 3D Flaw model used in this example consists of a stationary coil over a sheet of aluminum that contains a screw hole. Inside of the screw hole, a flaw is to be detected by two Hall effect sensors, which are used to measure the horizontal differential flux density. MagNet's 3D Transient solver correctly models induced eddy currents inside the aluminum plate, after the current in the coil is turned off.

WFNDEC Benchmark #2 - Eddy Current Inspection of Inconel Pipe The World Federation of Non-Destructive Evaluation Centers (WFNDEC) publishes benchmark problems for Non-Destructive Evaluation and Non-Destructive Testing (NDE/NDT) applications. The Second Eddy Current benchmark involves the inspection of an Inconel pipe using an internal pancake coil situated with its axis perpendicular to the axis of the pipe. Small defects of various depths in the external wall of the pipe are scanned in the axial and circumferential directions. Defects are detected as a change in the impedance of the coil.
