Given that,
Number of turns, N = 25
Magnetic field, B = 1.5 T
The coil has a crosssectional area of 0.80 m2
The coil exits the field in 1.0 s.
To find,
Induced emf in the coil.
Solution,
The induced emf in the coil is given by :
[tex]\epsilon=\dfrac{-d\phi}{dt}\\\\=\dfrac{dB}{dt}\\\\=\dfrac{NBA}{t}\\\\=\dfrac{25\times 1.5\times 0.8}{1}\\\\=30\ V[/tex]
So, the induced emf in the coil is 30 V.
