An inductive heater is sort of like a transformer with a shorted … WebSolution: Induced emf, ε = − d ϕ B d t = – ( 6 × 10 − 3 – 12 × 10 − 3) 0.01 = 6 × 10 − 3 10 − 2 = 0.6 V. Example 2: A long solenoid having 15 turns per cm and a small loop area of 2 cm 2 is placed in a solenoid to its axis. Find the induced emf in the loop while the current carried by the solenoid is changing steadily from 2. ...
