In this video I will explain visually the meaning of line integrals: work done by a force along a line (curve), and a magnetic field formed by current I along a wire.

Next video in the series can be seen at:

Thanks for the great visuals sir. My text books are sadly lacking in these, making it very difficult to understand. But your visuals have helped me enormously.

+Michel van Biezen, thanks for the examples, helped clear line integrals a bit!

In your work done example, it seems you are saying that if your "curtain" is twice as tall as your example (meaning doubling the height in the z direction) then you do twice as much work because it doubles the scalar value of the integral result. It would seem that pushing a block along the curve would not be twice as hard if you doubled your height. Thanks

Hatoff sir for your efforts...
I am your biggest fan.
