How would using a stronger permanent magnet help optimize the simple motor?

• It would allow more electricity to flow through causing it to spin faster

• It would reduce the amount of friction within the electrical field

• It would strengthen the magnetic field, allowing for a stronger push and pull

• It would reverse the N and S poles of the permanent magnet
