1) A) Marwin is performing the Lorentz force lab experiment and he has found that the pair-coil has 120 turns, has a radius of 0.15 m, and is carrying a current of 1.5 A. What is the magnitude of the magnetic field in the pair-coil apparatus? Express your answer in milliiteslas,mT, and use three significant figures.
B) Eliza is performing the Lorentz force lab experiment and she is deflecting the beam to the circle on the plate with a radius of 2.0 cm. What is the radius of the circular path of the electron beam? Express your answer in meters, m.
C) During the experiment, Eliza should be sure that the current through the field connections never exceeds what value? Express your answer in amps, A.
D) Suppose that the electron beam was bent to strike the outer circle on the plate within the electron tube by the magnetic field. If the electrons were slowed down (due to a decreased plate potential difference), how would the radius of the circular motion be affected? Consider Eq. 3 in choosing your response.
a) The radius would stay the same because even though the electrons will move more slowly, the magnetic force will be weaker.
b) The radius would decrease.
c) The radius would increase.
d) The electrons wouldn’t be able to enter the tube because the gravitational force would be too strong compared to the electrical force.

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...
