Thanks Gerry, Yes I am aware of the fact it can take any path. I believe
thats a required property for perpetula motion machines not to exist .
I am rusty on the cross product/dot product too. If I remember correctly the
first is orthogonal and the later is scaler.

Yes I forgot the permittivity so it is dependent on the capacitance. The 4pi
must be something to do with the units. I will have to work on that.
