14. In an experiment, protons are accelerated to different velocities and then subjected to a constant perpendicular magnetic field. The radii of the paths of the protons are measured against their velocities. The data is shown below.

A conducting rod is moved perpendicular to an external magnetic field with a velocity of 5.0 m/s as shown below. The rod is sliding on conducting rails that have a resistance of 0.25 2. the induced current is 0.80 A, what is the strength of the magnetic field? (ans: 0.16T) PHYSICS 12 b. Determine the magnitude of the magnetic field involved. (ans: 0.078 T) WCLN.ca Electrons replace the protons in the above experiment. The slope of the line will now be: (circle best answer).
