A conducting rod with a length of 0.45 m makes a contact with two conducting and parallel rails. The rails are connected to a 2.5 resistor; ignore the resistance of the rod Ω and rails. A constant force F moves the rod at a constant speed 4.2 m/s to the right with no friction between the rod and rails. The apparatus is placed in a uniform magnetic field 1.8 T that is perpendicular to the rails and the rod. Calculate the induced emf in the rod. Find the direction of the induced current in the resistor. Calculate the magnitude of the induced current in the resistor. Calculate the power dissipated in the resistor during the time when the rod moves in the field. Calculate the external force necessary to move the rod at constant speed through the magnetic field. A 2.0 m conducting rod is connected to a 6.0 V battery by two very light wires. The rod is moved at a constant speed of 2.8 m/s in a perpendicular magnetic field with a
