1. Suppose that you accidentally use your left hand, instead of your right hand to determine the direction of the magnetic force that acts on a positive charge moving in a magnetic field. Can you get the correct answer? Why? a. Yes, because the direction you get will be perpendicular to the correct direction. b. Yes, because the direction you get will be opposite to the correct direction. c. No, because the direction you get will be perpendicular to the correct direction. d. No, because the direction you get will be opposite to the correct direction. 2. Two particles, having the same charge but different velocities, are moving in a constant magnetic field. Between the two particles, which of them experiences the greater magnetic force? If, Particle 1 moves perpendicular to the field, and Particle 2 moves slightly faster than particle 1 at an angle with respect to the field. a. Particle 1 experiences the greater force, because it is moving perpendicular to the magnetic field. b.…

1. Consider a beam of electrons that moves from the electron gun towards the screen of a cathode ray tube due to the potential difference of 15kV. A pair of coils are placed outside a cathode ray tube and produce a uniform magnetic field of 250 μT across the tube. Calculate the force experienced by the electrons if the magnetic field is in place: a. parallel with the direction of the beam. b. Perpendicular with the direction of the beam. c. 50 degrees with the direction of the beam.

1. A wire carrying a 40-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.42-N force on the 4.3 cm of wire in the field. What is the average magnetic field strength? Things to Prepare: 1. Draw a sketch of the scenario in your notebook. Draw a vector respresenting the average magnetic field generated by the strong magnet. As no other information is given, the vector can be drawn in any diretion. Draw the current-carrying wire with respect to the field vector drawn above, making sure that it is perpendicular to the field. B= T
