Question

Suppose the compass needle was initially oriented so that the arrowhead were pointing (i) directly to the right of the page; (ii) directly to the left of the page; (iii) directly up the page; (iv) directly down the page; (v) to the upper-right corner of the page; (vi) to the upper-left corner of the page; (vii) to the lower-right corner of the page; (viii) to the lower-left corner of the page. In each of the cases described, what is the direction of the torque that the magnetic field described in part (a), where magnetic field lines point to the right of the page, exerts on the compass needle? You may describe the direction of the torque as clockwise (CW) , counterclockwise (CCW) , or no torque (0) . Note that a clockwise torque, for example, will try to rotate the needle in a clockwise fashion (so that if it were initially pointing straight up towards ‘12 o’clock’ it will begin to rotate towards ‘3 o’clock’).
