Permanent magnets
A permanent magnet (in contrast to an electromagnet).
Tapes depend on their magnetic properties to hold the data loaded, so storing a magnet next to them could well upset the information on the tapes
why should you keep diskettes away from magnetic sources
The bar is called a keeper or a magnetic keeper. It helps to preserve and maintain the strength of the magnet by completing the magnetic circuit and preventing the loss of magnetism.
Some staplers have small magnetic strips to help keep staples in place, but in general, staplers are not inherently magnetic.
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
The usual setup is called a generator. The basic idea here is that a piece of wire moves through a magnetic field; this will cause an electrical current. The electrical current causes another magnetic field that opposes the movement, so it requires (mechanical) energy to keep it moving.The usual setup is called a generator.

It can. Yes, stainless steel still has some magnetic properties, although minute, the detectors are quite sensitive
Diskettes contain magnetic material that stores data. If they come into contact with a strong magnetic source, such as a magnet, it can disrupt the magnetic fields and corrupt the data stored on the diskette, rendering it unreadable. To protect the data integrity, it's important to keep diskettes away from magnetic sources.
Well, darling, apart from iron, you might find a magnet getting cozy with nickel and cobalt. These metals have some magnetic properties that make them irresistible to magnets. So, if you're looking to spice up your magnetic collection, those are the ones to keep an eye on.
Are you asking what material is a compass needle made from? It that is your question, you need to keep in mind that the material used must have magnetic properties. Research the Iron Triad from the Periodic Table.
