As current travels within a conductor, _______________.
Understand the Problem
The question is asking about the behavior of magnetic fields in relation to electric current flowing through a conductor. It is looking for the correct statement that describes this relationship.
Answer
A magnetic field is developed around it.
As current travels within a conductor, a magnetic field is developed around it.
Answer for screen readers
As current travels within a conductor, a magnetic field is developed around it.
More Information
This phenomenon is described by Ampère's circuital law, which relates the circulating magnetic field in proportion to the electric current passing through a conductor.
Tips
A common mistake is to assume that the magnetic field either aids or resists the flow of current; instead, it simply forms around the conductor.
