Flux Variation-EMF generation!
A magnetic field (\(B\)), uniform between two magnets can be determined by measuring the induced voltage in the loop as it is pulled through the gap at uniform speed \(20 m/sec\). Size of magnet is \(2 cm × 1cm × 2cm\) and size of coil \(4 cm × 6 cm\) as shown in figure. The correct variation of induced emf with time is :
(Assume at t = 0, the coil enters the magnetic field)
