Question

An inductor furnace exploits eddy currents to melt metals and is often used to produce alloys or to grow crystals of conducting materials. A particular induction furnace uses a 15-turn solenoid of length 25 cm and radius 3.4 cm. The current in the solenoid oscillates sinusoidally according to I = Imax sin(ωt) where Imax = 2.4 A and ω = 1.29 107 rad/s. What is the maximum voltage induced across the solenoid? Neglect any resistance. V

Answer 1

induced voltage  is find out by farady law of electromagnetic induction .

first find flux linked with solenoid
