The electric field E is of course the force per unit charge on a test charge located
at the point, but when dimensions of atomic magnitude are considered, E may no
longer be considered uniform. Also, the average value of E over a region is not ...

If a current equal to that in the bounding circuit is considered to flow around each
element, the effects of coincident paths exactly cancel one another since they are
traversed in opposite directions and the net effect is simply that due to the ...

By Stokes's theorem <t>j = J" B • ds = <£,k . dl, This is the energy from the point of
view of closed filamentary circuits that may be considered to be distributed in any
way throughout a conductor or series of conductors. The sum of the current ...
