According to Biot Savart's Law, the field due to a current element carrying current I at a distance is given by
How do we approach further to find the field due to an arbitrarily shaped wire using Biot Savart,s Law?
Follow the given problem solving strategy.

A current flows in a infinitely long wire with cross section in the form of a semicircular ring of radius R. The magnitude of the magnetic induction at its axis is
