1. (a) The magnetic circuit shown here has a current of 10A in the coil of 2000 turns. Assume that all branches have the same cross section of 2 cm².

The core is made of Cobalt. Evaluate the ratio of induced MMF in the core to induced MMF in the air gap. (b) Each pair below contains an electrical term and its magnetic equivalent term. Box the wrong pair. (i) R and R(ii) ɛ and µ(iii) I and ý(iv) E and H.
