an magnet is a object that attracts or repel
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
A generator is a machine that uses a magnet to produce electricity. As the magnet rotates within coils of wire, it induces an electric current to flow, generating electrical power.

Every machine with a motor has a magnet. If you plug it in, it has a magnet. If you put in batteries or recharge it, it has a magnet. An automatic pencil sharpener uses magnets. A computer printer uses magnets. A refrigerator motor uses magnets. An electric razor uses magnets. A fan uses magnets. Hair cutters use magnets. Nose clippers use magnets. Look around your room and see what else uses a motor.
magneto
A magnet uses the electro-magnetic force. This force also includes electricity. Very basically, it works by electrons exchanging a proton. So a magnet doesn't use energy.

The permanent magnet always retains its magnetism so even the smallest temporary magnets will stick to it. its uses will include keeping the refrigerator door sealed nice and tight as well as the actual door being a permanent magnet so pictures and notes to the kids can be hung on it.
The spring system uses mechanical force to store and release energy, while the magnet system uses magnetic force. The spring system relies on compression and expansion of a spring, while the magnet system relies on attraction and repulsion of magnets.
