The apparatus below is submerged in a uniform, constant magnetic field, B. A conducting bar moves to the left at a constant speed v on two conducting rails joined as shown. As a result of the bar moving through this constant magnetic field, a current I is induced in the indicated direction. Which one of the following directions is that of B? a) Toward the right b) Toward the left c) Parallel to the long axis of the bar d) Into...
A metal bar is being pushed to the right along a U shaped conducting rail in the presence of a constant magnetic field. This induces a clockwise current as shown in the figure below. The green arrow represents the pushing force. In which direction does the original magnetic field point? - Select one: a. Up b. Down c. Into the screen d. Out of the screen e. To the right
3. The wire shown below is moving in the presence of a magnetic field. With the information given in the figure, determine the magnitude and direction of the induced voltage in the wire. v= 1 m/s B=0.5 T I = 0.5 m
As shown in the figure, a metal bar is in contact with a pair of parallel rails and is in motion with an upward velocity of magnitude v. A uniform magnetic field is present, directed downward as shown. The direction of the induced magnetic field (as a result of the induced emf) is Upward No magnetic field is induced. From b to a о не 1. What is the aldol addition product formed from the reaction of the following compound...
A metal bar 1.5 m in length moves in a direction perpendicular to a uniform magnetic field of magnitude 0.85T with a speed of 2.2 m/s. Determine the magnitude of the induced electric field in the metal bar.
The figure shows a region of uniform magnetic field directed into the page, surrounded by regions where the magnetic field is zero. A square coil of wire is moving to the right across the figure in snapshots. When the coil is moving out of the region of non-zero magnetic field. a) On the figure, draw the direction of the induced current in the wire loop. If there is no induced current, explicitly state that. b) Draw the direction of the...
A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...
In the following figure, the magnetic field is decreasing. Which figure represents the induced electric field? Select one: a. b. c. * C
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 0.344 m long metal bar is pulled to the left by an applied force F. The bar rides on parallel metal rails connected through a 44.1 2 resistor, as shown in the following figure(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 0.602 T magnetic field that is directed out of the plane of the figure. Part A At the instant when the bar is...
