Please correct me if I'm wrong, it's been a long time since I did my BAK test and any actual flying. But the dual Magneto's have two functions.

No 1 Safety (Main reason) - having a redundant ignition system, one gets damaged the other one is still operational.

No 2 Performance (Minor) - Having the two sparkpugs firing (Some aircraft with converted non aero engines have the dual magnetos hooked up to the single spark plugs so this dosent apply) gives a more even burn of the fuel in the combustion chamber which leads to a more efficent burn. In practice this only amounts to a small percentage increase in performance. When your doing your engine run up and you switch to a single magneto, your RPM only drops a few percent (in a 152 you run your engine up to 1700RPM and the maximum drop allowed is about 125RPM) The check is mainly used to check to see if both magnetos are actually running

Cheers!
