Induced Electric Field in a Solenoid
A solenoid with n turns per unit length carries a current given by I(t) = I₀sin(ωt). What is the magnitude of the induced electric field at a distance r from the central axis, for a point inside the solenoid?

μ₀nI₀ωcos(ωt)/2r
B
μ₀nI₀ωrsin(ωt)/2
C
μ₀nI₀ωrcos(ωt)/2
D
μ₀nI₀sin(ωt)/r
