Electromagnetism. F = qvB sin theta, equation for a particle in a field. For a straight wire, F = IlB sin theta. B = permeability of free space/2pi * I/r. B is for magnetic field, it is measured in Teslas (T). v is velocity (m/s) of particle in the field, q is its charge in.
F = qvB sin ?, where ? is the angle between the directions of v and B. This force is often called the Lorentz force. In fact, this is how we define the magnetic field strength B—in terms of the force on a charged particle moving in a magnetic field.

Magnetism. Cloud chambers are a simple method of detecting high energy charged particles. In order to detect the particles, the chamber is filled with a supersaturated vapor of water or alcohol. High speed particles disrupt the vapor and leave a trail. As radiation passes through the chamber only charged particles are visible. This is because neutral particles don’t disrupt the vapor.
