# What is the strength of the magnetic field around a thin, long straight conductor?

A Magnetic field is generally interpreted as a region where the force of magnetism acts. This force of magnetism is mainly produced as a result of a moving charges or some magnetic material.

Form finely long straight current-carrying conductor magnetic field; B = MoI/4πa

= B ∝ 1/a

Magnetic field intensity is inversely proportional to the distance from the conductor.

Therefore, the explanation is inversely proportional to the distance from the conductor.

Note:

Characteristics of the magnetic field due to a current-carrying conductor

• It encircles the conductor.
• It lies in a plane perpendicular to the conductor.
• The reversal in direction of current flow reverses the direction of the field.
• The strength of the field is directly proportional to the magnitude of the current.
• The strength of the field is inversely proportional to the distance of the point from the wire.
