don't permanent magnets lose their strength over time ?

• Proven 8y ago
  Of course - that's why they're called "permanent"

  No. Unless you heat them very hot. They'll have software to stop them getting too hot, so the magnetism will effectively last forever

    How can software lower tempurature? Limiting maximum usage, like clocking down a cpu? If so, to keep the magnets from going bad, they have to slow the car down at times. That sounds bad. I Dont mind if my cpu loses 500Mhz, but my car not accelerating could be a safety problem

      Gas engines also have over temperature problems. Indeed, there is an entire cooling system do deal with it. Mostly, as long as that is working and you aren’t going full throttle on an extremely warm day you don’t have to think about it. Any mechanical assembly will have a maximum working temperature, it’s just a matter of figuring out witch critical component will fail first and planning accordingly.
