Audio is encoded on the cassette tape by aligning the magnetic field of the material on the tape. A magnet can erase the tape or perhaps corrupt the sound quality.
Rubbing a nail with a magnet will align some of the magnetic domains in the nail. This will have the effect of making the nail into a magnet. The nail won't be a strong magnet, but it will come away with some residual magnetism. Suggestion: try a simple experiment with a nail and a magnet and some small paper clips to see if this works.
To make a magnet by stroking, you can rub a piece of iron or steel with an existing magnet in the same direction multiple times. This process aligns the magnetic domains within the material, creating a magnetic field in the iron or steel.
When you rub a pin with a magnet, the pin's domains align in the same direction as the magnetic field produced by the magnet. This alignment leads to the pin becoming magnetized, with its own north and south poles.
Move towards the U magnet so that the poles attach.
Jam/Jelly has no effect on the magnet or its magnetism, but it will cause the magnet to become sloppy and sticky.
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
Rubbing a needle on a magnet will align the domains within the needle in the same direction as the magnetic field of the magnet. This causes the needle to become magnetized and exhibit magnetic properties itself.
if you have a magnet and a magnetic matereal, rub the magnet from one end of it to the other. do this several times and it will eventualy be a magnet.
Yes - distorted or even erased.
You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
Rub a magnet with another metal...
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.
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the permanent magnet.
Rub the metallic surface with a magnet.
A VCR (Video Cassette Recorder) uses electromagnets in the record, playback, and erase heads. An erase head can also have a permanent magnet in it.
rub metal in one direction repeatadly on a magnet
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
