The apparatus shown in the diagram can be used to demonstrate the force on a current carrying conductor when the conductor is inside the magnetic field. The apparatus is placed in a magnetic field. When the switch is closed, the copper rod rolls along the aluminium rods. L power supply copper rod aluminium rods Find the force (in newton) acting on the rod of length L = 22 cm which has a resistance of 116 in the presence of magnetic field of strength 0.8 T. The power supply provides a potential difference of 14 V.
