First, you should get to know your magnet well.
1.Strong Magnetic force, if possible, make a hole to fix magnet
2.Usually Ni coating, very smooth, if possible, get them rough enough
3.Max working temp. (Different grades have different working temp.) , with high temp., magnet will demagnetize.

Second, to choose an adhesive, you should pay more attention to the application environment.
Different adhesive, the application is different. E.g. Temp. Humidity, Oil condition and so on. You should tell adhesive professional all details and ask them to recommend the best for you.
