Thanks fatra2 and espen180 for your quick reply. Actually I'm thinking about a lightning strike which is acting on a conductive plate. The current flows from the attachment point to the whole plate in a radial way in all directions. The plate can be assumed as isotropic.
The magnetic field...
Dear all,
I've found in many books forces acting between 2 parallel wires, but not between a magnetic field and a surface. Let's now imagine a conducting plate which is within a magnetic field. Which is the resultant force acting on that panel?
Many thanks in advance!
