1 point A proton is moving along the v axis toward positive 3:. A magnetic field pointing toward positive 2 is switched on. The proton then: experiences no force experiences a force pushing it toward positive x experiences a force pushing it toward negative x experiences a force pushing it toward positive v experiences a force pushing it toward negative v experiences a force pushing it toward positive 2 experiences a force pushing it toward negative 2 1 point E? This diagram shows a conducting loop connected to a gaivanometer. The large arrows represent a uniform magnetic field, and show that the magnetic field magnitude is decreasing from, m T down to 5 T over a twosecond period. As this happensr current flows and so the galvanometer needle deflects as shown. lit :> i: \"51'\" *HH' Suppose now that the magnetic field is oriented in a different direction, as shown here: f While it is in this orientation; the magnetic field increases from 8 T to 13 T over a two-second period. In that case, during the time the field is increasing, no currentflows the same amount of current flows as in the first case, and it ows in the same direction more current flows than in the rst case, out it flows in the same direction less current flows than in theflrst case. but it flows in the same direction the same amount of current flows as in the first case, but it flows in the opposite direction more current flows than in the rst case, and it flows in the opposite direction less current flows than in theflrst case, and itflows in the opposite direction 1 point 5 A conducting loop is in a region where there is a magnetic field. \"Initial" refers to the situation at a given moment in time; and "final\" refers to the situation a few seconds later. Consider the following cases {B = angle between B and normal to plane of loop}: (I) Burma-I = 5T: Bm = 51 Ham-ml = 13"; Hwy = {in {3) Burma-I =11": Bm = IT Elmer = 0"; Bjm! = 90 {3} 3mm = 2T;- Bm = IT Bin-arid = 1]\"; am} = {in The cases in which a current will flow in the conducting loop are: one only two only three only one and two only one and three onlyr two and three only all three cases none of the three cases 8 1 point Suppose you lower a large bar magnet on top of the loop described in #1, with the south pole of the magnet closer to the loop (i.e., long axis [N-S axis] of the magnet perpendicular to plane of loop). What should you expect to happen: O Loop will experience no attraction, no repulsion, and no torque. Loop will be repelled away from the magnet. Loop will be neither attracted nor repelled, but will experience a torque. O Loop will be attracted toward the magnet. 9 1 point A wire loop is sitting in a magnetic field. The field is pointing perpendicular to the plane of the loop. Which of these fields will cause the largest magnitude of current to flow in the loop? O Initial value 10 T, constant Initial value 10 T, increasing at 2 T/s Initial value 40 T, increasing at 1 T/s O Initial value 5 T, decreasing at 3 T/s O Initial value 20 T, constant1 point }? Twe long straight wires. parallel to each other. are separated by 12 m. Thea.f carry.r currents in the same directien; the current in wireA is double the current in wire 3. The points at which the net magnetic eld is zero are how far from wire A? 10m There are no points with zero net magnetic eld. The net magnetic eld is zero at all points between the wires
