Magnetic trailer lights have a protective coating on the magnets to keep them from damaging the paint on the vehicle being towed.
They also cannot make contact with "ground" through the paint, even if the protective coating was missing.
The answer is, no they do not ground through the magnet.

Why does your trailer lights go out when you hit the brakes on your f 150?
You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.
