I have made such plugs but I make the magnet an interference fit and also apply JB Weld. Never had a problem.

On the subject of temperatures, I drove back home from East Kirkby Airshow yesterday, near 50 miles of A road driving with a couple of miles of 30 limit to get to home.
I immediately sampled engine temperatures with my infrared thermometer, having switched off as soon as I got home so no idling, just about 60 seconds of standing. When the sump had no airflow past it and hot oil from around the engine had a chance to drop down to the sump.
Thermostat Housing - 92 C
Engine Temp Sensor area of the Head - 88 C
Top of the Radiator (at water level, not the air gap) 85 C
Sump - 80 C
So that bears out the numbers Mike has mentioned.
