Question

# A square, single turn coil 0.20m on a side is placed with itsplane perpendicular to a constant magnetic field. An EMF of 18mV isinduced in the coil winding when the area of the coil decreases ata rate of 0.10m^2/s. What is the magnitude of the magneticfield?

Use formula $$\displaystyle{E}={\frac{{N\times{B}\times{A}}}{{{t}}}}$$ where E = 18 mV.
