Coil
d = 19mm

Principle
The eddy currents will penetrate
the conductive plate according
to the skin depth δδδδ
22
δδ==
µ µωσ
o r
For the TEAM 7 project the plate
is made of copper which is 19mm
thick and the frequency is 200 Hz.
δ=5.77mm
δδδδ is a little less than three skin depths

Current Density in Plate
The mesh is automatically refined
in the area where the gradient of
the field is the greatest
