Would a moving electron go in a clockwise or counter-clockwise circle? (Hint: try both directions, and see which direction is consistent with the magnetic force.) Note that we're not asking what magnetic field is made by the moving electron, but what effect the coil's magnetic field has on the moving electron. Read the eBook Section 21.1 2. 4/4 points | Previous Answers MI3 21.1.X.035 An alpha particle (consisting of two protons and two neutrons) is moving in a circle at constant speed, perpendicular to a uniform magnetic field applied by some current-carrying coils. The alpha particle makes one clockwise revolution every 80 nanoseconds (see the figure).
