In this lesson on Interaction Between Fields, which is part of Unit 3 Area of Study 1 for VCE Physics, you will learn how to:
- describe the interaction of two fields, allowing that electric charges, magnetic poles and current carrying conductors can either attract or repel, whereas masses only attract each other.
Interaction Between Two Parallel Current-Carrying Wires
The interaction between two parallel current-carrying wires is a magnetic interaction which depends on the following factors:
- Current and its direction
- The length of the wire
- How far apart they are
The force on a single wire:F = BIL sin(\theta)
Why does a moving charge generate a magnetic field?
This video will explain the answer to this question.
