Asked by Pat
A wire loop has an area of 0.12 m2, and the magnetic field through it increases from 0 to 0.20 T in 0.30 s. What is the induced emf in the loop?

ε = - dΦ/dt =- d(B•A•cosα)/dt.
If cos α =±1, then
ε =A•(Δ B/Δt) =
= A•(B2 –B1)/ Δt =
= 0.12•0.2/0.3 =0.08 V
If cos α =±1, then
ε =A•(Δ B/Δt) =
= A•(B2 –B1)/ Δt =
= 0.12•0.2/0.3 =0.08 V
