It seems like it is because ∫s.dF doesn't have a physical meaning so we can't use it to find work done?
So for a force vs displacement graph, ∫F.ds is talking about the area under the curve and the x-axis while ∫s.dF is talking about the area bounded by the curve and the y-axis. Hence ∫s.dF...
It means that when current is flowing through a straight wire, how is magnetic field created around that wire? That is, what happens in the wire which causes this phenomenon to occur?
And why does the magnetic field change direction (from clockwise to anticlockwise or vice versa) when the...
When current is allowed to flow through an electric conductor, magnetic fields are produced. What actually causes the magnetic fields to appear?
