Magnetic Field Due to Circular Current Carrying Wire: Practice Problem & Solution

A wire carrying current I has the configuration as shown in Fig. Two semi-infinite straight sections both tangent to the same circle are connected by a circular arc of central angle θ, along the circumference of the circle, with all sections lying in the same plane. If the magnetic field at the centre of the circle is zero, then θ is: Magnetic Field Due to Circular Current Carrying Wire diagram: A wire carrying current I has the configuration
