To understand the origin of the torque on a current loop due to the magnetic forces on the current-carrying wires.
this problem will show you how to calculate the torque on a magnetic dipole in a uniform magnetic field. we start with a rectangular current loop, the shape of which allows us to calculate the lorentz forces explicitly. then we generalize our result. even if you already know the general formula to solve this problem, you might find it instructive to discover where it comes from.
a) give a more general expression for the magnitude of the torque τ. rewrite the answer found in part a in terms of the magnitude of the magnetic dipole moment of the current loop m. define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ϕ, noting that this angle is the complement of angle θ in part a.
give your answer in terms of the magnetic moment m, magnetic field b, and Ï•.

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
