Hi,

I have this problem I dont find the solution. It is due tomorrow.

Find the magnetic field vector H produced atthe origin (0,0)by the wire shape shown in the figure (attached), the dimension of the rectangle are 2a x 2b, its center is aligned with the origin, Current carried by the wire is I.

(it seems to have a typo for the dimension of the rectangle the one on the figure should be the good ones)

For me it seems to cancel each other, but does not seem right.
