A professor of mine has stated that when designing a martian rover, you want it to be able to apply enough torque to the wheels to climb a verticle wall (providing there was an arbitrary normal force).
I was able to do that, but the problem I was having was that if the torque provided by...
When a particle with electric charge q moves with speed v in a plane perpendicular to a magnetic field B, there is a magnetic force at right angles to the motion with magnitude qvB, and the particle moves in a circle of radius r. This formula for the magnetic force is correct even if the speed...
