Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 161 cm , but its circumference is decreasing at a constant rate of 15.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 1.00 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Find the magnitude of the emf E induced in the loop after exactly time 9.00 s has passed since the circumference of the loop started to decrease. Find the direction of the induced current in the loop as viewed looking along the direction of the magnetic field. Please explain all steps
A circular loop of wire with radius 0.0480 m and resistance 0.163 Ω is in a region of spatially uniform magnetic field, as shown in the following figure (Figure 1). The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value of 7.88 T and is decreasing at a rate of -0.696 T/s . Is the induced current in the loop clockwise or counterclockwise? What is the rate at which electrical energy is being dissipated by the resistance of the loop? Please explain all steps
A 0.333 m long metal bar is pulled to the left by an applied force F and moves to the left at a constant speed of 5.90 m/s. The bar rides on parallel metal rails connected through a 46.7 Ω resistor, as shown in (Figure 1), so the apparatus makes a complete circuit. You can ignore the resistance of the bar and rails. The circuit is in a uniform 0.625 T magnetic field that is directed out of the plane of the figure. Is the induced current in the circuit clockwise or counterclockwise? What is the rate at which the applied force is doing work on the bar? Please explain all steps

The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T. The electromagnetic force on the rod…arrow_forward
