How do you, say, throw a ball?
You hold the ball in your hand, and then you swing your arm, and THEN you RELEASE. If you don’t release the ball, all the energy you use to swing is wasted, and you start from the beginning, with a ball in your hand.
An electrical motor (most conventional ones) use pairs of electromagnets to move the moving parts a.k.a Rotor. The idea is, you power the closest magnet first to pull the rotor towards it. At certain point, the motor will switch off (or release) this pair, and power up the next pair. And the cycle of powering on a pair and then switching to the next continues to keep the motor moving.
This is the reason motors use electromagnets, magnets that can be turned on and off with electricity. A permanent magnet cannot turn on and off on command like that, so you end up swinging but not releasing the ball, which is useless.
Energy = force * distance. If you have two magnets attracting each other, you can get a little energy out by letting them move towards each other, but then you’d have to put that same energy right back in to move them away from each other, plus any energy that went to useful work, friction, and other losses.
At best you’re making an energy storage device, but not a very good one compared to a flywheel or battery.
tl;dr: the magnets push just as much slowing you down as they do speeding you up.

Because there’s no power. It’s like dropping a bouncy ball. Sure the ball bounces, but eventually it will stop if you don’t continue to bounce it. The ball doesn’t have any power of its own. Just like the magnets.

Each magnet pulls the rotor towards itself, so at first a magnet in front of the rotor accelerates it. But for the rotor to rotate further, it needs to move away from the magnet it was just being attracted to again, and that uses about as much energy as the rotor gained from the previous attraction. In sum, nothing is added or gained and you would’ve been better off not using any magnets at all.
