Basically the second Magneto is provided as a fail safe. There are a lot of redundancies in aviation, especially when it comes to maintenance and safety. The second magneto on a single engine plane is there to contine to provide a spark to the engine in case of a failure of the first magneto.
There are two sets of spark plugs for each piston, there are dual magnetos that create spark for each set of plugs this is a redundant system to increase safety. If one of the magneto is not working properly when you do your mag check the plane is not considered safe to fly, performance will be decreased and the redundancy of the system is gone.

The characteristics of the aircraft KFM 112M is a four cylinder with dual ignition and is meant to be designed for an ultralight aircraft and motor glides.
Magnetos
improved engine performance.
principle in magnetos striction
Aircraft have an optimum flight level where it can achieve speed against minimal dual burn
Important products of this industry include armatures, starting motors, alternators, and generators for automobiles and aircraft, and ignition apparatus for internal combustion engines, including spark plugs, magnetos, coils, and distributors.
Switch from both magnetos to left and right individually and note the RPM differences. You need to check the individual aircraft's POH, but a drop of more than 150, or a difference of more than 75 between the sides is typically cause for concern.
It has not been possible to find a range of toys made by Magnetos. There is a range of building sets manufactured by Guidecraft called Magneatos. The toys consist of a range of panels and clips to make all sorts of shapes and buildings.
There are some iphones that do have dual sim cards.
Some of the physical activities that the aircraft mechanics do is the erecting of ladders, repair and maintenance of the aircraft.
