A toroidal solenoid has 500 turns, cross-sectional area 6.25 cm^2, and mean radius 4.00 cm. (a) Calculate the coil's selfinductance. (b) If the current decreases uniformly from 5.00 A to 2.00 A in 3.00 ms, calculate the self-induced emf in the coil. (c) The current is directed from terminal a of the coil to terminal b. Is the direction of the induced emf from a to b or from b to a? | Numerade

A toroidal coil has a mean radius of 16 cm and a cross-sectional area of 0.25 cm^2 ; it is wound uniformly with 1000 turns. A second toroidal coil of 750 turns is wound uniformly over the first coil. Ignoring the variation of the magnetic field within a toroid, determine the mutual inductance of the two coils. | Numerade

Commonwealth Fusion Systems on Instagram: "It’s a great moment to celebrate milestones at CFS — in more ways than one. Today we announced we’re done manufacturing one of our key magnets and putting it through a rigorous, month-long battery of performance tests — which it passed. That achievement unlocked a payment from @energy's Milestone Based Fusion Development Program, an important fusion energy industry catalyst, after DOE’s panel of experts validated our results. Marking the occasion on Mon
