Strength of the Magnetic Field

What does the strength of the magnetic field produced by a current-carrying wire depend on?

You know that a current-carrying wire produces a magnetic field, and you can figure out the direction of the magnetic field using the right-hand rule. What does the strength of the magnetic field depend on? Watch the video below to find out about the strength of the magnetic field in a current-carrying wire.

Question

What does the magnetic field in a current-carrying wire depend on?

The strength of the magnetic field through a current-carrying wire is directly proportional to the current through the wire and inversely proportional to the distance from the wire.
