A magnetic field is produced by the current passing through a long straight wire. When will the strength of the magnetic field increase?

A magnetic field is produced by the current passing through a long straight wire. When the distance between the magnetic field and the wire decreases, the strength of the magnetic field increases.

A metallic wire carrying an electric current has associated with a magnetic field. The magnitude of the magnetic field produced at a given point increases as the current through the wire increases. The magnetic field produced by a given current in the conductor decreases as the distance from it increases.
