Homework Statement
On a thin infinite metal plate, which is ##d## thick and has got electric conductivity ##\sigma ##, two electrodes are applied. The distance between the electrodes is ##r## and the potential is ##U##.
Describe the magnetic field anywhere in space. Ignore the contribution of the lines that bring the current to electrodes.
Homework Equations
The Attempt at a Solution
I don't really know what would be the smartest way to start this problem.
Basically, if I understand the problem correctly, I can imagine the two electrodes as two electric charges and on that plane I should get currents like this http://www.phy.ntnu.edu.tw/ntnujava/snapshotejs/twopointcharges_2_20090117112750.gif . Now for a given point in 3D space I would have to somehow integrate over the entire metal plate. That's if I am not completely wrong.
Hmmm.. Why do you suggest? How should I start?
