A conducting bar that is \(\ell=40 \mathrm{~mm}\) long can slide with negligible friction on two parallel conducting rails positioned at an incline of \(\theta=15^{\circ}\) (Figure P29.66). Initially, the bar is at rest in a magnetic field of magnitude \(B=0.60 \mathrm{~T}\). What is the emf between the rails \(0.20 \mathrm{~s}\) after the bar starts sliding while it is still inside the magnetic field?
