#24. Where do I start?
tery, A or B, is the positive terminal of the battery? ilai ul the bät instant shown in the diagram. Explain. *23. A horseshoe magnet is sitting on a table with its north pole on the lef, as sh current-carrying wire also lies on the table, with the current passing between the pole as shown. A s of the magnet at 45° to the magnetic field, as shown. In what direction will there be a force acting on the wire? Current carried toward the flor **28. A picture shown. *24. The figure at right shows the top view of a compass next to a N wire. The north pole of the compass is indicated by an arrow (i.e., north is to the top of the page in the diagram). When a switch is closed, a current is carried through the wire, downward into the floor as indicated. In which direction, clockwise or counterclock- wise, does the compass rotate? Explain. a)11 A in B in Compass b) A **25. Two wires carry current into the page as shown below left. One wire carries a current and the other carries a current 21. Which of the arrows below right best represents the mag netic field at point A, a point that is the same distance from both wires? Justify youransiet. *29. Tw direction in the pla A? If so, i clockwise 21 a) b)Explanation / Answer
When swith is closed current in the wire flows into the floor.
This current produces magnetic field towards left at the point where compass is located
So compass will rotate anticlockwise to point net magnetic field in North west direction
