Rectangular loop with sides of length a= 1.30 cm and b= 3.80 cm is placed near a wire that carries a current t?
*** a rectangular loop with sides of length a= 1.30 cm and b= 3.80 cm is placed near a wire that carries a current that varies as a function of time: it=3.80 + 1.01t^2 where the current is in Amperes and the time is in seconds. The distance from the straight wire to the closest side of the loop is d= 0.490 cm.

___________

*** What is the magnetic flux through the loop at time t= 1.80 seconds? (Define positive flux into the page.)
___________

*** What is the induced e.m.f. in the loop at time t= 1.80 seconds? (Note that positive emf is clockwise.)
________

for the dirst one I tried to use the equations of Tesla . I failed, there left one try *** help me to solve it ,
I got 7.025*10^-8!!
