A magnetic circuit consists of silicon steel of 3000 permeability and an air gap. The length of the steel core is 10cm and the air gap is 2 cm. Both have the same cross-section of 1.5 sq.cm. A current of 1/4 A flows through the windings to produce 2351 maxwells flux. How many turns are there in the coil? Answer: ______ turns Through two parallel wires A and B, 10A and 2A of currents are passed respectively in opposite directions. If the wire A is infinitely long and the length of the wire B is 2m, then force on the conductor B, which is situated at 10 mm distance from A, will be ______ N.
