PART B Thinking/Inquiry 9 marks 6. The diagram to the right shows an electron entering a magnetic field, B. The arrow indicates the direction of the electron's velocity. a. List the steps involved in determining the direction of the magnetic force on the electron as it enters the magnetic field. [2] b. On the diagram above, use a solid line to sketch the direction of the magnetic force (FM) acting on the electron. [1] c. On the diagram above, sketch a possible path that the electron might take as it travels through the magnetic field. [1] 7. A proton moves into a magnetic field with an initial velocity of 4.1 x 10 m/s [left], perpendicular to the field. It experiences a magnetic force of 3.1 x 10 N [into the page]. a. Determine the magnetic field strength of the field that the proton has entered (include both magnitude and direction). [3] b. Determine the radius of the proton's circular path. [2]
