PHY 134 Lecture Notes - Lecture 5: Voltage Source, Current Source
Document Summary
The point of this lab is to understand the relationship among the force exerted on a current carrying wire, magnetic field strength, and the length of the wire. A current carrying wire of length l in a magnetic field b will have the force exerted on it: We will be using a very strong magnetic so it is important to very cautious when using. In this equation, represents a vector whose magnitude is the length of the wire and direction is the direction of the current flow in the wire. The represents the strength of the current and the magnetic field vector is represented by . We will be passing a copper wire between the two magnets, held in place by wooden blocks, and a weight is attached to the other end. The wire is also touching a 3 current leads, one above the magnets, and two below them.
