Question #73273

A coil of wire is arranged with its plane perpendicular to a uniform magnetic field o flux density B. when the radius of the coil increases from r1 to r2 in time Δt then what is the emf induced in the coil ?

Options:

A) ωB/r22-r12/Δt

B) ωB(r2-r1)2/Δt

C) ωB(r22-r12)/Δt

D) ωB(r22+r12)/Δt

Answer: A coil of wire is arranged with its plane perpendicular to a uniform magnetic field o flux density B. when the radius of the coil increases from r1 to r2 in time Δt then what is the emf induced in the coil ωB(r22-r12)/Δt.
