A ﬂat coil of wire consisting of 56 turns, each with an area of 39 cm^2, is positioned perpendicularly to a uniform magnetic ﬁeld that increases its magnitude at a constant rate from
3.1 T to 10 T in 5.7 s. If the coil has a total
resistance of 0.56 Ω, what is the magnitude of
the induced current?
Answer in units of A
ℇ=ΔΦ/Δt = N•Δ(B•Acosα)/ Δt=
I= N•A•ΔB/Δt•R= ...
