Question 1 (1 point) A charged particle that is moving in a static uniform magnetic field may experience a magnetic force, but its speed will not change O will always experience a magnetic force, regardless of its direction of motion O may experience a magnetic force which will cause its speed to change ONone of the above Question 2 (1 point) An electron moving in the +y direction, at right angles to a magnetic field, experiences a magnetic force in the -x direction. The direction of the magnetic field is in the O +x direction -z direction O +z direction -x direction O +y direction Question 3 (1 point) Consider a long bar magnet. If we were to map the strength of the magnetic field around the magnet, it would O) Be proportional to how close the point is to the South pole only O Be proportional to how close the point is to either pole on the magnet O Be proportional to how close a point is to the magnet, whether the pole or not Be uniform everywhere in spaceQuestion 4 (1 point) The direction of magnetic field lines are O) The direction of magnetic force a positive charge would feel if placed there The direction the needle of a compass would point if placed there Both of the above ONeither of the above Question 5 (1 point) If you were standing at the Earth's south magnetic pole (which is near the geographic north pole), and had a compass, where would you expect the compass needle to point? O Nowhere, the magnetic field is zero there The needle would spin in every direction O Downwards into the ground O Upwards into the sky Question 6 (1 point) Two long parallel wires are placed side-by-side on a horizontal table. If the wires carry current in the same direction, O the wires push away from each other O the wires pull toward each other both wires are lifted slightly ONone of the choices O one wire is lifted slightly while the other is forced downward against the table's surfaceQuestion 7 (1 point) A horizontal wire carries a current straight toward you. From your point of view, the magnetic field caused by this current O points directly towards you O points directly away from you O circles the wire in a counter-clockwise direction O points to the left O circles the wire in a clockwise direction Question 8 (1 point) An ideal solenoid with 400 turns has a radius of 0.040 m and is 40 cm long. If this solenoid carries a current of 12 A, what is the magnitude of the magnetic field at the center of the solenoid? (u_0 = 4piE-7 Tm/A) 6.0 mT 9.0 mT 16 mT 4.9 mT 15 mT Question 9 (1 point) A particle in a mass spectrometer, moving at a speed of 7.50x10 m/s enters a magnetic field of 0.200 T. If the radius of curvature for the particle is 8.60 cm, what is the mass to charge ratio of the particle, in kgC? Your Answer: Answer units
