Has anybody remagnetized a rotary on-off mag base before? I was

How are these magnetized at the factory?


Is this a mag base to mount an antenna on a car roof?

Why not get a bunch of old hard drive (rare earth) magnets, and just
epoxy them onto the bottom of the existing mag base, and cover with
some
thin felt for protection?

indicator.

The rotary switch that turns the magnetic pull on or off is essential
for many machinist uses.
