Question
you may answer the questions on this sheet or on a separate sheet. You need not provide an explanation or any of your answers. A metal wire is placed near two bar magnets as shown in the pictures below. Using the Front View as reference, if the left end of the wire is connected the + terminal of a battery and the right end of the wire is connected to the - terminal of the same battery, the wire must deflect out of the page. deflect into the page. deflect up along the page and into the page (diagonally). deflect down along the page and out of the page (diagonally). not move. Using the Front View as reference, if the ends of the wire are connected to the terminals of ammeter and the wire is quickly moved down along the page, the ammeter must detect current directed left to right. current directed right to left. current directed out of the page. current directed into the page. no current. Using the Front View as reference, if the ends of the wire are connected to the terminals of an ammeter and the wire is quickly moved in some direction. If the ammeter detects no current, the direction of motion of the wire could be out of the page. into the page. up along the page. down along the page. left along the page.Explanation / Answer
This whole question is based on Lenz law of magnetism n electrycity.
1) D : as current flow from left to right, then there is current induce in the wire which pushes it down the page n out of page so that magnetic feild around it doesn't change.
2) D
3) C
