A magnet can erase details on the magnetic strip of your ATM credit or debit card if it's placed in close proximity to them. Needless to say, this can cause a great deal of inconvenience and embarrassement at a time when least needed !!!

Neither or both.
Iron, cobalt and nickel are ferromagnetic metals.

Three uses of a permanent magnet are: 1. In the needles of compasses which are used to navigate airplanes and ships; 2. In fridge door seals, to hold the doors closed; 3. In loudspeakers and microphones, which need to have permanent magnets as well as electromagnets to work.
A kettle does not have a magnetic force on its own. However, since it is metal, it can attract a magnet.
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.

You can remagnetize a magnet by rubbing a good magnet along the bad one. Do this a few times. Be sure to rub the magnet in only one direction.
Neither or both.
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.

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.
there are no bad uses of hydro electricity and cant be
