No, but placing a video tape on a speaker will ruin the tape

No but it can ruin other parts of the computer like the harddrive.
well if a yellow light of deaf from overheating (witch mine did) a magnet can
Salt can ruin anything made of metal or steel
To make a magnet you can do it three ways. No1. Get a metal rod and wrap some Insulated copper wire around it. You can use some other wires but it might not work as well. Make sure the wire isn't too thick. Wrap the wire 50+ times. Connect the two ends of the wire to a battery. Don't connect it to a strong power source as it will get very hot very quickly. Now the rod is a magnet until the battery dies or you cut off the current. Also; now the iron rod now has become a weak permanent magnet. The more current you add to it the more stronger it will be and the longer you have the battery on the stronger it will be.. Also, don't drop it as it will lose it's magnetic properties. No2. Get a magnet. The stronger the better. Rub the magnet up a piece of metal then when you get to the end take the magnet off the metal and take it back to the start making sure the magnet doesn't touch the metal. I don't really like this method as it takes a long time to get the metal to pick up anything decent. No3. Get a magnet and let it stick to a piece of metal. The piece of metal will be weak but enough to make the needle on a compass move. (Don't ruin a compass. Mine point south-west and it shouldn't do that...)

Magnetic badge holders are used by companies that would rather use a magnet instead of metal clips and pins that could ruin the clothing. It would be more towards business men and females who wear suits.
You can do it by: 1) Stroking -stronking an iron bar with one of a magnet in one direction will the iron bar into a weak but permanent object 2) Heating and hammering- take a steel bar, put it under a magnetic field. Hit and hammer it. We get a permanent magnet. 3)By using direct current-Put a steel bar into a solenoid. Turn on the power supply. Remove the steel bar and after a while it will be magnetised.
the island of ruin
you have to go to ruin valley and use cut on the metal door and there is the sapphire
A magnet in a credit card is used to store information. The magnet encodes data in a series of magnetic stripes which are then read by card readers. This information typically includes the card number, expiration date, and cardholder's name.
when you sing METAL you have to use your diaphragm to scream you don't wanna use your throat to scrream because it will ruin your singing voice
