The two right hand rules were featured today as we tried our best to get a grip on what nature is like. The first right hand rule we encountered was the right hand rule for magnetic fields created by electric currents. As an exercise, you should be able to figure out the direction of the magnetic field created by the current in the loop shown below. Can you? We also reviewed the right hand rule for forces exerted by magnetic field on moving charged particles and on electric currents. Can you figure out the direction of the magnetic forces on the particle at the moment that it enters the magnetic fied and on the current in the diagrams above? We also saw this excellent 60-year-old video with sharply dressed MIT physicists! Comments are closed.
