24whats this ???
cant understand the fig
the strip is metallic n veryy thin n infinitely long
plz use amperes law
current though the plate is i........
the wholk ething is in 2D plane...
PLZ PLZ SOLVE BY AMPERES LAW!!]

1the green one is a metalic sdtrip infinitely long thoprugh which current i is flowing...
1THE ABOVE IS THE ANSWER BY BIOT SAVART LAW>....BUT GIVE ME THE SOLUTION BY AMPERES LAW
62if i have understood your diagram correclty, then what youy have given is a current in a infinite plate of thickness l2??
take a parallel rectangle to the plate at a distance l above and l below the plate...
then apply ampere's law
1but how???
the diagram is there is a very long thin horizontal plate......like a sheet of paper extended on two sides......n u will ahve to find the magnetic field at the distanbce l2 above the upper edge of the paper////the plate n the point is in 1 plane...now how to do it bhaiya???
62one more thing is current i or is current per unit lenght i?
because if the current is i, then the answer will be zero..
but if the current per lenght is i then the answer wud be μ0i/2
(assuming that what i have understood is correct :P)
1n we canot take a rectangle as u said....because magnetic field will not be the same on two adjacent sides...
1THERE IS AN INFINITE LONG METALLIC PLATE WITH WIDTH L2 and height 0[just like a cellotape openend up..:P]
a current i is flowing through it....find the magnetic field at a distance l2 aboce the upper side of the sheet.[not at a height l2,the whole apparatus is in 2D plane]
