A long thin wire is placed along the y-axis (just outside) of a frame of refernce. There exists a uniform magnetic field of `10^(-6)` T along the x-axis. Calculate the magnetic field at the points (0,0,2m),(0,2m,0) and (2m,0,0) when the wire carries 10A current. Revise the calculation for a thick wire.

Answer

`2 xx 10^(-6)`T, `infity`, `sqrt(2) xx 10^(-6)`T, `2 xx 10^(-6)`T, `10^(-6)`T, `sqrt(2)xx 10^(-6)`T
