let me start with saying I've missed a few lectures so im learning this online.


http://en.wikipedia.org/wiki/Magnetic_field

First part under 'Maxwell's equations' section
V being the triangle thing, which i take to mean d/dx+d/dy+d/dz

Which gives you a result in the i direction, nothing in j,k (y,z).

Honestly ive never seen Z before, do you mind showing me the equations you used ?

C)
This is just the cross product of the perpendicular electric and magnetic fields and is correct  ?
