Question

a magnetic flux linked with a coil of 500 turns become 0 from 0.32Weber in 0.1 second find the induced EMF produced in the wire​

Answer 1

Answer:

A nonconducting insulating ring of mass m and radius R, having charge Q uniformly distributed over its circumference is hanging by an insulated thread with the help of a small smooth ring (not rigidly fixed with bigger ring). A time varying magnetic field B=B

0

sinωt is switched on at t = 0 and the ring is released at the same time. The induced EMF in loop at time t=2π/ω is:

77248

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
