... Multiple Choice 1. (b) Torques from the magnetic force on the top and bottom wire cancel and any force on the wire on the left contributes no torque, so we only need to consider the wire on the right. Since everything is nice and perpendicular, τ = rF = rIlB = (0.3 m)(2 A)(0.3 m)(0.05 T) = 0.009 N · ...

... ma* = FC + ΣFi + (q²/4m){B [Br]}. If the applied magnetic field is weak, then the last term is very small (being of the order of B²) and can be neglected. If FC + ΣFi is negligible, then we have ma* = (q²/4m){B [Br]}. Let’s first look at the direction of this “centrifugal” type term. [Br] has ...
