Electric field strength

Can anyone advise me of the approxiate electric field strength (V/m) generated by an eddy current probe in a weakly conductive medium (e.g. inconel or hastalloy)?
I recognise that there can be a lot of variables to this "approximation" so an order of magnitude will be adequate.

Re: Electric field strength
Hi, Ed,

You have only specified the specimens under test.

There is no way to give you an estimation. It varies even for an approximation. You have to specify the parameters of the coil and the current flowing in the coil in order to get a close guess.

For the parameters of the coil, you have to tell me or estimate the inner diameter of the coil, the outer diameter of the coil, the height of the coil and number of turns of the coil. Please specify the current intensity and the driving frequency as well. I will calculate it for you once I have those parameters.
