Is it possible to have a magnet with three poles?
(c) Yes, there can be a magnet with three poles, again when like poles of two magnets are glued together.
Can magnets have multiple poles?
Bar magnets have two magnetic poles – north and south. The magnetic field around a bar magnet is called a dipole magnetic field. Sometimes magnetic fields have six or even eight poles (an octupole!). Any field with more than two poles is called a multipole field.
What are the only 3 magnetic elements?
Since then only three elements on the periodic table have been found to be ferromagnetic at room temperature—iron (Fe), cobalt (Co), and nickel (Ni).
What are some examples of temporary magnets?
Paperclips, iron nails and other similar items are examples of temporary magnets.
Does unlike poles attract each other?
Unlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750.
Can magnets have 4 poles?
Well bar magnets have two poles, so their magnetic fields are called dipole which means–you guessed it–two poles! But some magnets have more than two poles. In fact, some have four, or six, or even eight!
Is there a magnet with only one pole?
In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). A magnetic monopole would have a net north or south “magnetic charge”.
Which magnets are temporary magnets?
Common temporary magnets include nails and paperclips, which can be picked up or moved by a strong magnet. Another type of temporary magnet is an electromagnet which only retains magnetism when an electrical current is running through it.
Is bar magnet a temporary magnet?
Bar magnets are permanent magnets. This means that their magnetism is there all the time and cannot be turned on or off as it can with electromagnets .
