A metal bar of mass 500 g slides outward at a constant speed of 1.5 cm/s over two parallel rails separated by a distance of 30 cm which are part of a U-shaped conductor. There is a uniform magnetic field of magnitude 2 T pointing out of the page over the entire area. The railings and metal bar have an equivalent resistance of 150Ω.150Ω. (a) Determine the induced current, both magnitude and direction. (b) Find the direction of the induced...

A zero resistance rod is sliding west along two zero resistance rails that are 2.3 m apart, on the ground where the earth’s magnetic field is nearly vertical with a magnitude of 0.60 mT. the bar is moving with a velocity 60 m/s. As it moves through the earth’s magnetic field an EMF is generated that creates a current flowing through the rails. a far away western resistance completes the circuit with a 5 Ω. What is voltage difference across...

As shown in the figure below, a metal rod is pulled to the right at constant speed v, perpendicular to a uniform magnetic field directed out of the screen. The bar rides on frictionless metal rails connected through a resistor forming a complete circuit. The length of the bar between the rails is 5 cm, the magnitude of the magnetic field is 0.4 T, the resistor has a value of 102. What speed of the rod is required to produce...

A 1.50-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.5T magnetic field. The bar rides on parallel metal rails connected through R = 24.0Ω, as shown in the figure below, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. a) (5.0 pts) Calculate the magnitude of the emf induced in the circuit. b) (5.0 pts) Find the direction of the current induced in the...

A conducting rod of length 4.5 m is sliding downward between two vertical rails without friction. The rails have negligible resistance, but the resistance of the rod is 0.8 Ω. The rails are connected to an 23.3-Ω resistor, and the entire apparatus is placed in a 0.1-T uniform magnetic field. The rod is sliding down at the constant velocity of 7.4 m/s. What is the value of the constant current generated in the rod?

4, A conductive bar of length L = 0.8 m is pulled to the left at a constant velocity of 1.8 m/s. A magnetic field of magnitude 0.06 T is directed out of the page. a) What is the induced voltage in the loop? (10 pts.) What is the magnitude and direction of the induced current, if the resistance of the circuit is 2.5 Ω? (5 pts.) b) As the induced current passes through the movable bar, it couples to...
