timer base missing big chunk of magnet

Hi, I have a 200hp 1989 evinrude and I lost spark suddenly. Following the shop manual I troubleshooted until I reached the sensor coil resistance test. The timer base failed this test, i removed and inspected it. I noticed one of the (magnets?) had a big chunk missing out of it. The other was in tact and flush. I've attached pictures, not sure if they're magnets or just electrical contact strips. But anyways, this probably would be my problem right? Prior to losing spark, i was having a hard time getting the motor started. It would fire, the bendix would pop down and then die immediately. could the timer base cause that problem too?

Also what would cause the timer base to wear out like that. just time?
Thank you.
