When the switch is closed in the circuit shown in the sketch in Figure 22-7, the wire between the poles of the horseshoe magnet deflects upward. From this you can conclude that the left end of the magnet is
A) a south magnetic pole C) not contributing to the wire's deflection. B) a north magnetic pole. D) a magnetic monopole
according to the concept of the electro magnetic induction
basing on the concept of lenz law
the current entreing in to the side of the magnet pole and the current leaving side of the magnet is north pole
so here we observed the circut the left end of the magnet is current entreing side and the right side is current leaving side
so the left end of the magnet is south pole
the correct option is A

22. A portion of a loop of wire passes between the poles of a magnet as shown. We are viewing the circuit from above. When the switch is closed and a current passes through the circuit, what is the movement, if any, of the wire between the poles of the magnet? S switch A) The wire moves toward the north pole of the magnet. B) The wire moves toward the south pole of the magnet. C) The wire moves upward...
The figure shows a wire that is connected to a power supply and suspended between the poles of a magnet. When the switch is closed, the wire deflects in the direction shown.Which of the dashed boxes A-D represents the position of the north magnetic pole? Choose one A, B, C, or D.

Name: PHY-2323 Test III (5 points) A horseshoe magnet is held vertically with the North Pole on the left and the South Pole on the right. A wire passing between the poles is equidistant from them, and carries current directly away from you. In what direction is the force on the wire? 8. (10 points) A lightning bolt may carry 10,000 A for a short period of time. What is the resultant magnetic field 100 m from the bolt
What will happen to the wire between the magnet poles when the switch S is close? P N V B switch Q Select one: a. Moves into the screen (or page) O b. Moves to the magnet's North pole oc Nothing. The wire remains in place O d. Moves out of the screen (or page) o e Moves to the magnet's South pole
I. As shown below, a coil is in a magnetic field that is directed upward. If the magnitude of the magnetic field increases, in what direction does the induced current flow in the coil? Explain 2. Suppose you know that a deflection of the galvanometer needle to the right means that current is flowing into the galvanometer as indica ted A bar magnet is moved towards a coil as shown in the picture below. The galvanotneter needle deflects to the...
Now suppose that the battery is removed and replaced with an ammeter. No current will flow through the wire because there is no energy source. Consider what will happen when a barmagnet is pushed toward the coil as shown in the figure below. When the coil "feels" the changing magnetic field caused by the approach of the bar magnet, it will thereby become energized; a current will begin to flow through it, and the ammeter will register that current. This...
Lab Homework - Force on a Current-Carrying Wire This homework will be due when you come to lab the week of November 4. A horseshoe magnet, with its north and south poles indicated, is shown in the figure below.
