Answer:

Maximum emf in the coil is 100 volt    

Explanation:

We have given number of loops in the coil N = 50

Cross sectional area [tex]A=0.2m^2[/tex]

Angular speed is given [tex]\omega =5rad/sec[/tex]

Magnetic field is given [tex]B=0.2T[/tex]

We have to find the maximum emf in the coil

Maximum emf in the coil is given by [tex]e=NBA\omega[/tex]

[tex]e=50\times 2\times 0.2\times 5=100volt[/tex]

So maximum emf induced in the coil is 100 volt
