If the magnetic flux linked with each turn of a coil having 60 turns varies at the rate of 1 Wb per hour, then the induced emf is volt.

Question

Accepted Answer

(3) 1/(60). Given: N=60; flux per turn changes at 1 Wb per hour. Idea: ε=N(dΦ)/(dt), with the rate in Wb s⁻¹. Convert: 1 h=3600 s, so (dΦ)/(dt)=1/(3600) Wb s⁻¹. ε=60×1/(3600)=1/(60). So ε=1/(60) V≈0.017 V.

If the magnetic flux linked with each turn of a coil having 60 turns varies at the rate of 1 Wb per hour, then the induced emf is ______ volt.
