Problem 27.4: Force on moving charges in a current carrying wire: find the direction of the field
Configuration 1: Field Off | Field On
Configuration 2: Field Off | Field On
Please wait for the animation to completely load.
The animation illustrates charged particles flowing through a wire (position is given in millimeters and time is given in seconds). A current consists of charges moving (1C/s = 1 ampere) through a conducting wire. Remember that in a conductor, charges are free to move in response to forces. Initially, there is no magnetic field in the region shown. The particles travel in one direction. Restart.
- What is the direction of the current in each case?
- What is the direction of the magnetic field in each case?
