No, generally a thicker cable is a better conductor because its resistance is lower. If it were merely a matter of surface conductivity this wouldn't necessarily be true. However, internal conductivity and surface conductivity can be affected by magnetic fields:

- amelius 11y agoThere is also a tendency for currents to creep towards the surface of the conductor at high frequencies, see [1], although this is ultimately also caused by internally generated electromagnetic fields.
