(b) : Given, Side length of square, $l=1 \mathrm{~m}$\ Resistance, $R=1 \Omega$\ Magnetic field, $B=0.5 \mathrm{~T}$\ The angle between the area vector and magnetic field is zero as the plane of coil is perpendicular to the magnetic field.\ Magnetic flux, $\phi=B A \cos 	heta$\ $\phi=0.5 	imes 1 	imes 1 	imes \cos 0^{\circ}=0.5 \mathrm{~Wb}$\
