a wire loop has an area of 0.12 m^2 and the magnetic field through it increase from 0 to 0.20 T in 0.30s. What is the induced emf in the loop

Respuesta :

04-05-2018

Induced emf = -NA (ΔФ/Δt)

N = 1 (assuming its 1 loop), ΔФ = 0.2-0 = 0.2 T, Δt = 0.3 sec, A = 0.12 m^2

Therefore,

Induced emf = -1*0.12*(0.2/0.3) = -0.08 V
