A cuent of 1.0 A is flowing though the coil. What is the toque on the coil? 1 I I I 4 B I Confi that the coil will expeience a foce based on the agnetic field and cuent diections supplied. Calculate the agnetic foce on one side. Deteine the distance,, fo the point of otation that the agnetic foce is applied. Using the ight-hand ule, confi that a foce applies on side out of the page. A foce applies to side 4 into the page. The coil will tun clockwise as viewed fo in font of side. Sides 1 and lie paallel to the agnetic field and no foce will apply. F IlB N length of side 4.0 c distance between axis of otation and application of foce 1 side length.0 c 0.00 Calculate the toque applied by the agnetic foce on one side of the coil. Since two sides, and 4, expeience a agnetic foce and hence a toque, the toque on one side should be ultiplied by to find the total toque. State also the diection of otation. τ F N Total toque N The diection is clockwise as viewed fo side.

Side PQ is paallel to the agnetic field. 5 Consideing the diection of the foces acting on sides PS and QR, the coil would otate in an anticlockwise diection. 6 D. The diection of the cuent does not affect the agnitude of the toque. This is the only option that doesn t affect eithe the distance to the axis of otation o the agnetic foce fo the options available. 7 τ F sides F N 8 F nilb N 9 Cuent flows into bush P and aound the coil fo V to X to Y to W. So foce on side VX is down, foce on side YW is up, so otation is anticlockwise. 10 D. As F nilb, the coil will expeience oe foce, and otate faste, if the cuent and field stength ae inceased. Theefoe, A and B ae coect. Whethe C is coect will depend on how the aea is inceased. But if the length in the field is inceased, you would expect it to tun faste. If widened, it will expeience oe toque but that ay not ake it tun faste. Section.
