Question

the change in magnetic Flux associated with a coil in 2 seconds is 10 webber. the magnitude of included emf produced in the coil in volts is​

Answer 1

Explanation:

Change n in magnetic flux Δϕ=1−10=−9 Weber

Time taken Δt=0.1 sec

So, emf induced in the coil E=−

Δt

Δϕ

⟹ E=−

0.1

(−9)

=90 Volts
