A square loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. The loop has total resistance of 0.8 ohms. It begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 T pointing into the page. Finally it leaves the field. 21) While entering the field what is the direction of the induced current as seen from above...
A 1.10-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.790-T magnetic field. The bar rides on parallel metal rails connected through R = 25.5-Ω, as shown in the figure (Figure 1), so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. A) Calculate the magnitude of the emf induced in the circuit. Express your answer using two significant figures. B)Find the direction of...
Magnetic Flux: A 0.95 m long metal bar is pulled to the right at a steady 7.1 m/s perpendicular to a uniform, 2.20 T magnetic field. The bar rides on parallel metal rails connected through R= 144 Ω, as shown, so that the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. What is the current in the wire and what direction does it flow (Clockwise or Counterclockwise)
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...
