- A solenoid sits in front of you and you are facing one end. You move the south end of a bar magnet further away from the end of the solenoid that you are facing. What will the direction of the induced current in the solenoid be as you move the bar magnet further from the solenoid (from your perspective)? clockwise counter-clockwiseQuestion 2 I h. I S A. В. С. D. As a conducting coil moves to the right at constant speed, it passes over the north pole of a magnet and then moves beyond it. Which graph best represents the current in the loop for the time of the motion? A counterclockwise current as viewed from above the loop is a positive current, clockwise is a negative current.6. For each situation, circle the best choice. a. A current carrying wire is pulled away from a conducting loop as shown. Which way will an induced current flow in the conducting loop? I- Clockwise in the loop, Counterclockwise in the loop, There is no induced current, More information is needed b. A metal bar completes a circuit as in moving upwards in a magnetic field as drawn. Which way will an induced current flow in the loop? Clockwise in the loop, Counterclockwise in the loop, There is no induced current, More information is needed
- Two high-current transmission lines carry currents of 45 A and 78 A in the same direction and are suspended parallel to each other 28 cm apart. If the vertical posts supporting these wires divide the lines into straight 16 m segments, what magnetic force does each segment exert on the other? _N. Exponential format with 2 SẺ. QUESTION 14 An induced emf will occur if A. the strength of the magnetic field is changed. B. the coil's area is changed. C. the angle at which the magnetic field and the coil's area meet is changed. D. all of the above.The generator in the figure uses a loop that rotates with a period T. Suppose the rotation rate (i.e. frequency) is increased so that the loop is made to rotate twice as fast. How will that affect the magnitude of the induced emf? Area - A J Horseshoe magnet N The magnitude of the induced emf will increase by a factor of two. O The magnitude of the induced emf will decrease by a factor of two The magnitude of the induced emf will increase by a factor of four. O The magnitude of the induced emf will decrease by a factor of four. O The magnitude of the induced emf will not change.Question 11
