In Figure, find the magnetic field at point P, which is at the common center of the two semicircular arcs.

Question

David · Accepted Answer

According to biot-savart law, the magnitude of the magnetic field due to a differential current 
carrying element Ids is given by
dB=u0I/4pi (|dsxr|/r^2
     =u0I/4pi * rdθ/r^2
     =u0I/4pir
For the outer arc we have,
Bouter=u0I/4pib
points out of the page
similarly for inner arc we have,

In Figure, find the magnetic field at point P, which is at the common center of the two semicircular arcs.
