In the net work shown in figure,find the magnetic field at the centre O of the coil.

The current loop abcde formed by two circular segments of radii r_1(=4cm) and r_2(=6cm) with common centre at O, carries a current I(=2A) as shown in figure. What is the magnetic field at the common centre O? What will be the value of magnetic field at O when theta=90^@ ?
