SOLUTION.

There is the Faraday's law( I am sorry, but I am not sure about correct spelling of the guy's name) which states that an emf induced in a closed circuit due to an external magnetic field is equal to:
Eemf = - /t.
Where  is the magnetic flux through the loop, in our case. The minus sign ...
