Dear all:

Any one could help me with this problem:

I want to use a matrix of data which describes the magnetic field(Bx, By, Bz) at point(x, y, z) in a column of space to calculate the the induced current in a closed loop on xy plane. Basically the surface integration of dot product of dB and dS. Is there a way to do that?

Any one could help please as soon.

Thanks a lot! Ruming

I have your data and file from your earlier Question, and provided your (1*108) vectors. What I don’t understand are what ‘B’ and ‘S’ are.

To create the derivatives, use the gradient function. The dot product is then straightforward to calculate.

Hi Star Strider,

Thank you for your help! What do you mean by "in terms of your data"?

Thanks!

I may still have your file.

Does it have any relevance to this Question, and if so, what?
