I've added a new article to my 6mm wargaming site covering some helpful info for the discerning gamer.
The article covers how to make burning markers of vehicles and aircraft to improve the look of your games. It is aimed at the 6mm gamer but can be scaled up (or down!) I guess. The direct link is http://6mm.wargaming.info/page505.shtml
No they just balance on top. Obviously for some vehicles it will be better than others. I did think of using a magnet as my tank generally have magnetised turrets but I decided it wasn't worth the extra effort.
I wondered if the question might have been about the base the vehicle is on, as the models aren't magnetic...
I've been mounting some of mine on magnetic sheet, and frequently see stryation similar to that on the edge of yours when I cut them.
The markers are Very Nice BTW, among the best I've seen.
I use the woodland scenics Autumn foam all the time for model railroading, and this never occured to me...

Your pardon, sir.
I didn't see the point of using a magnet on a non-ferous casting.
Rougher surface/more friction to prevent sliding then?
Good point. I'd probably try a disk punched out of sheet lead.
