A current of 10 A flows around a closed path in a circuit which is in the horizontal plane as shown in the figure. The circuit consists oi eight alternating arcs of radii r_1=0.08m and r_2 =0.12m . Each subtends the same angle at the centre. a. Find the magnetic field produced by this circuit at the centre. b. An infinitely long straight wire carrying as current of 10 A is passing through the centre of the above circuit vertically with the direction of the current being into the pane of the circuit. what is the force acting on the wire at the centre due to the current in the circuit? What is the force acting on the arc AC and the straight segment CD due to the current at the centre?
