For case (a), whatis the induced emf? induced current? direction of thecurrent?For case(b) what is the induced emf? induced current? direction of thecurrent?
For case(c) what is the induced emf? induced current? direction of thecurrent?
The figure shows a 10 - cm - diameter loop in three different magneticfields. The loop's resistance is 0.10 Omega. For case (a), whatis the induced emf? induced current? direction of thecurrent? For case(b) what is the induced emf? induced current? direction of thecurrent? For case(c) what is the induced emf? induced current? direction of thecurrent?
Explanation / Answer
a) the induce emf : = d/dt = S*dB/dt = *0.05^2*0.5 = 3.93x10^-3 V the induced current : I = /R = 39.3x10^-3 A Lenz's rule=> direction : clockwise b) the induce emf : = d/dt = S*dB/dt = *0.05^2*0.5 = 3.93x10^-3 V the induced current : I = /R = 39.3x10^-3 A Lenz's rule=> direction : clockwise c) there is no induce emf => =0 V => I =0 A
