Magnetic Field -- break in the continuity of a conductor

Hi! Just curious...
Does a break in the continuity of a conductor's volume affect its magnetic field, resistance, etc?

A continuous circuit is necessary for an electric current and an electric current of charges is required to generate a magnetic field. Now if you mean a nick in the volume, then resistance is proportional to the effective area of the conductor.

thanks for the reply.
what if the cross-sectional area of a conductor is not uniform, say there are microscopic fractures in a certain region, is there some way to detect this?
Does this make sense?

Sure, makes sense, and yes, many ways. Reflectometry from my experience, or merely resistance of the conductor.

this is just amazing! does reflectometry work even for low-frequency radiation? I only know xray reflectometry.
