Charges and Currents in Magnetic Fields Study Guide for Chapter 30 Outline 1. Circular Motion in a Uniform Magnetic Field A charged particle moving perpendiuclar to a uniform magnetic field will travel in a circle. The radius of this circle is given by the formula    where is the mass of the particle, is its velocity, is its charge, and is the magnetic field. Problems: 5, 53 2. Force on a Wire The force of a magnetic field on a segment of current-carrying wire is given by the formula: F L B    Here is the current and is the (the vector from the beginning of the wire to the L length vector end of the wire). Problems: 21, 25, 51 3. Torque on a Loop The of a loop of current is a vector with magnitude
