The magnetic field near a current carrying wire is directly proportional to the distance from the wire.

Question

Quizplus · Accepted Answer

The magnetic field near a current carrying wire is directly proportional to the inverse of the distance from the wire. This relationship is described by the formula B = μ0I/2πr, where B is the magnetic field strength, μ0 is the permeability of free space, I is the current in the wire, and r is the distance from the wire. As r increases, the magnetic field strength decreases, but not in a linear manner. Therefore, the statement is false.
