Question: 3 20 points a toroid has a radius of 05...

Question details

3. (20 points) A toroid has a radius of 0.5 m and cross sectional area 104 m2. The total number of turns of wire is N 1000. The current in the wire is 1-0.01 sin (100 t).D,-+D × 10-7 in our SI units a) Find the magnetic field B(t) inside the toroid. b) Find the magnetic flux IB (i) inside the toroid. c) Express the induced voltage on one turn of the wire,in terms of dl/dt. What is the inductance L, for one turn of the wire? e) What is the induced voltage V() for the whole toroid? Take
