3. A current-carrying wire placed in a magnetic field will be deflected by a force that is proportional to: (check all that apply) the current flowing through the wire the length of wire in the magnetic field the type of wire moving in the magnetic field the strength of the magnetic field6. A proton moves with an unknown velocity through a magnetic field of 3.45 x 10"T that points directly north. The proton experiences a force of 2.40 x 10" N directly east. What is the magnitude of the velocity? (charge of a proton is +1.6 x 10" - C) 6.35 x 108 m/S 4.35 x 10 m/s 8.85 x 105 m/s 4.35 x 10 m/s9. A particle of charge 2.4 x 10" C is stationary in a magnetic field of 3.20 T. What is the electric force on the particle caused by the magnetic field? 7.68 x 10-18 N O ON 8.62 x 10-20 N 7.50 x 10-19 N10. Which of the following are true? Check all that apply. If the two current-carrying wires are placed parallel to one another and the current is moving in opposite directions, the force between them will be attractive. If you place a current-carrying wire in a magnetic field, the wire will experience a magnetic force produced by that magnetic field. If the two current-carrying wires are placed parallel to one another and the current is moving in the same direction, the force between them will be attractive. A current-carrying wire produces a magnetic field around it that moves in a direction given by the right-hand rule for a current-carrying conductor
