You ask good questions, here are my thoughts:
"Does the magnet get stronger when the engine is run for a while"
I DO NOT see the magnetic rotor gaining any magnetic field strength when the engine is running, nor loosing any either. However, as the mag turns faster (or if the magnet were stronger) more energy can be stored in the coil.
"or do you need to remove the magnet and have it' magnetism renewed?"
I'm NOT a fan of removing the magnetic rotor out of the armature because in the process its similar to removing the "keeper" on say a horseshoe magnet. Thats NOT to say rotors cant be magnetically recharged or may require it if they have been removed long periods, I'm ONLY saying theres usually no need to have on charged up as running the engine DOES NOT use up their magnetism.
I usually agree with Bobs excellent answers, for whatever that's worth ???

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
