Physics 1402A/B Lecture Notes - Lecture 5: Cross Product
Document Summary
Lecture 5 notes 2 - parallel wires interactions. So, we now know that wires carrying current in a magnetic field will experience a force because of the impact of the magnetic field on the moving charged particles. We also know that the wire carrying a current will generate a magnetic field which can be measured by the biot-savart law. What is the impact of each field on the other. Let"s explore this concept a little further in this section of the lecture. Recall that the magnetic field proceed by current i1 is: where d is the distance from the wire in any direction, and the direction of this b field is given by a rhr. Well, if we have a setup of two parallel wires that are close to each other like below. Well we prefaced earlier that we know that it experiences a force! Thus, each wire will exert a force on the other.
