1. Mr. Lewis conducted an experiment to measure the magnitude of a uniform magnetic field, electrons were accelerated from rest through a potential difference of 500 V and then enter a uniform magnetic field that is perpendicular to the velocity vector of the electrons. The electrons travelled along a path because of the magnetic force exerted on them, and the radius of the path is measured to be 12.5 cm. a. What is the magnitude of the magnetic field in Oersteds? b. What is the angular speed of the electrons in revolutions per minute? c. What if sudden voltage surge causes the accelerating voltage to increase 700 V. How does that affect the angular speed of the electrons, assuming the magnetic field remains constant? d. If Mr. Lewis decides to conduct this experiment in a non-uniform field, explain and sketch the motion of electrons.
