Explanation / Answer

According to the concept of the electro magnetic induction

Given that

Length L=0.24 m

Radius r=0.01 m

Number of turns N=375 turns

Magnetic field B=575*10^-4 T

Angle =51°

Now we find the magnetic flux

Magnetic flux =NBAcos(theta)

=375*575*10^-4 *3.14*0.01^2*cos51

=42.61*10^-4 Weber

Now we find the magnitude of the induced emf

Induced emf=/t=42.61*10^-4*/1.4

=30.4*10^-4V
