When a small piece of wire passes between the magnetic poles of a horse-shoe magnet in 0.1 sec, emf of `4 xx 10^(–3)` volt is induced in it. The magnetic flux between the poles is :

A small piece of wire is passed through the gap between the poles of a magnet in 0.1 sec. An e.m.f. of 4 xx 10^(​–8) ​volts is induced in the wire. The magnetic flux between the poles (in weber) is:
