3 Questions
What is the relationship between a moving charge and magnetism?
A moving charge produces a magnetic field
How does the direction of the magnetic field around a straight current-carrying conductor change with the direction of current?
The direction of the magnetic field follows the right-hand rule
What happens to the strength of a magnetic field as the distance from a current-carrying wire increases?
The strength of the magnetic field decreases with distance
Test your knowledge on the relationship between moving charges and magnetism, the direction of magnetic fields around current-carrying conductors, and how the strength of magnetic fields changes with distance from a current-carrying wire.
