If the object to be picked up is magnetizable, the magnet temporarily magnetizes it allowing it to be picked up. If the object to be picked up is not magnetizable, then it remains unmagnetized and cannot be picked up.
it would have to be a rock containing the mineral Iron. which would then have to be magnetized to create a temporary magnet, or a permanent magnet if prepared properly
You can make a temporary magnet by rubbing a piece of iron or steel with a permanent magnet. This aligns the domains in the material, creating a magnetic field. However, this magnetism will fade over time as the domains become disorganized again.
Yes. But the attached paper clip will usually not generate a magnetic field as strong as the magnet itself. At some point, either the field will be too weak to pick up another clip, or the weight of the clips will exceed the lifting power of the original magnet. The magnetic field is not affected by water. In fact, the slight reduction in weight due to the buoyancy will normally allow a slightly larger string to be formed underwater than in air.
Magnets have a polarity which is generated by exposing them to a stronger magnetic field during manufacture. They can be polarized through any two faces on the magnet. Typically long skinny magnets are magnetized end to end. Flat magnets are magnetized side to side. Neodymium magnets are relatively strong, and frequently magnetized between flat faces. The magnetic field is very weak on the sides, and very strong at the ends (faces that were polarized).
The number of paperclips a bar magnet can pick up will depend on the strength of the magnet and the size of the paperclips. In general, a typical bar magnet can pick up several small paperclips at once.
Yes - if you have a powerful enough magnet !
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
No
Yes, a magnet can pick up steel BBs because steel contains iron, which is a magnetic material. The magnet will attract the steel BBs due to their magnetic properties.
It will pick up the nails the same way a bar magnet would do!
You can test if something is a magnet by seeing if it attracts certain materials like iron, cobalt, or nickel. Another way to test is by observing if the object can pick up small metal objects like paperclips. Additionally, you can use a compass to see if the object can affect its direction when brought close to it.
The easiest way to check for steel is to use a magnet. A magnet is going to pick up steel and will not pick up metals that do not contain iron.
