Answer:
Rate of magnetic field is 15923.668 T/sec
Explanation:
We have given radius of loop conductor r = 2 mm = 0.002 m
Induced emf = 2 volt
As the magnetic field and plane are perpendicular to each other so angle between magnetic field and area is 0°
Cross sectional area of the conductor is equal to [tex]A=\pi r^2[/tex]
[tex]A=3.14\times 0.002^2=1.256\times 10^{-6}m^2[/tex]
Induced emf is given by [tex]e=\frac{-d\Phi }{dt}=-A\frac{dB}{dt}[/tex]
[tex]2=1.256\times 10^{-6}\times \frac{dB}{dt}[/tex]
[tex]\frac{dB}{dt}=159235.668T/sec[/tex]
