\textbf{177-} A coil has $500$ turns and the area of each loop is $120\,\text{cm}^2$. In a uniform magnetic field perpendicular to the plane of the coil, with a constant time base, the EMF varies and the graph of the driving force versus time is as shown in the figure below. What is the magnitude of the magnetic field in Tesla?
