So for an infinite plane of current, current traveling in the X direction, the magnetic field everywhere above the plane is going clockwise, and the m. field below the plane is going counterclockwise.
So the path integral is Integral of H dot dl = Current Enclosed
Why, in this video, does the path integral NOT equal 0?
Isnt the top path going from Y = -L to L, and the bottom path going from Y = -L to L?
So you get ∫H ⋅ dl = ∫Hydirection⋅ ⋅ dyydirection + ∫Hnegativeydirection⋅ ⋅ dynegativeydirection
Then you get Hy, y from -L to L, plus Hy, y from L to -L?
So you get H(L - -L) + H(-L - L), and you get 2HL-2HL = 0?
