Q.  The resistance of a coil is 10  Ω and number of turns is 1000. The magnetic flux linked with the coil at a moment is 5.5  ×   10 - 4  Wb. After 0.1 sec the magnetic flux reduced to  to 0.5  ×   10 - 4   Wb. Then (i) Find electromotive force and (ii) what is the value of flowing charge?

Dear Student,
1) Produced emf =-1000×(0.5×10-4-5.5×10-4).1=5Vand 2) charge in .1  second =510×.1=5mC
Regards
