Verify Magnetic Induction Homework: 50A Copper Wire 0.5*10-2m

[QUOTE="Delta2, post: 6100424, member: 189563"] I think you got the correct answer but with the wrong way. The main mistake in your approach is that the current is not flowing in that thin greyed strip but it is evenly distributed through the volume of the wire. Because we have cylindrical symmetry in this problem , and also we are interested for the magnetic field on the surface (what it is following will not be correct if we are interested for the magnetic field in the interior of the wire) , you can assume that the current is flowing through a thin line that coincides with the central axis of the wire. Calculate then the magnetic field at distance ##r=\frac{d}{2}## from the center (that is where the surface of the wire is located) where ##d## is the diameter of the wire. EDIT: BTW, the statement of the problem is a bit misleading. We are interested for the magnetic field intensity, not the magnetic induction. [/QUOTE]
