Compression test

I don’t expect much metal shavings after such low mileage but what magnets do you folks use ?
The cheaper magnets which are quite common normally loose it’s magnetic power at temperatures higher than 80 degree Celsius. I think air cooled engines normally run at higher temperatures.

@scooterfan,
yes, didn't think about degaussing.
Used such one from my "pin-board". For sure cheap stuff.
But during checking and cleaning this little mesh filter, this coil-spring still stuck magnetically on.
Good to be reminded about basic physical law.
Will test at next oil-change.
