How does rubbing a magnet along an iron nail create a temporary magnet?

No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because the process of magnetization has to do with electromagnetic induction rather than physical contact.
You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.

∙ 14y agoBy rubbing a magnet along an iron nail magnetic domains in the nail all align in a common direction, which causes each magnetic domain to add to the next and give the nail temporary magnetic properties.

Why does stroking a material with a magnet make it magnetised?
because the magnet causes particles called electrons in the atoms of the nail to align along the magnet's lines of force. The atoms with aligned electrons then act like tiny bar magnets themselves.
How do you make a magnet with two south poles or north poles?
It is not possible to create a magnet with two south poles or two north poles. Both the poles always exist along with each other. Force 2 magnets together end to end with the south poles together. You will get a north pole at each end and a big south pole in the middle. This arrangement is called a quadrupole.
Can a magnet cause an electric current to flow through a wire?
You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil. However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.
How can you determine the poles of an odd shaped magnet?
You place the magnet under a piece of paper, and then sprinkle some iron filings on the paper. The iron filings will line up along the magnetic lines of force, which will show very clearly where the magnetic poles are.
Why are the poles of a magnet called N and S?
When a magnet is freely suspended at its center it will set itself along the north-south direction. The tip pointing towards the geographical north direction is called the north pole and the other tip is called the south pole.
How do you remagnitize a magnet?
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.
Why is banging a temporary magnet on a hard surface demagnetize it?
The magnetic properties of a temporary magnet are derived from the fact that its molecules are aligned along the magnetic polarity: they mostly point in the same direction and so one end of the temporary magnet is North and the other is South. Banging the magnet can knock some of these molecules out of alignment so that they face random directions. As a result, there is no particular direction in which is then North and South and so magnetism is reduced. When enough molecules have been knocked out of alignment you are left with a demagnetised piece of metal.
What are the parts of a magnet and the effect of breaking a magnet?
parts of a magnet-1. north pole2. south polethe breaking of a magnet form new magnets.when breaking is done along the axis ,pole strength decrease and along perpendicular axis it does not change.
How is the world a magnet?
The magnet is in the world because magnetism is one of the fundamental forces of the universe, along with gravity.
Explain how a metal can become a temporary magnet?
Real quick FYI, temporary magnets are also called electromagnets :) A really simple electromagnet is an iron nail with with copper wire (can be insulated or uninsulated) wrapped around it. At the ends, attach a 9-volt battery to the negative and positive terminals. And voila! To "turn-off" the magnetism, just remove one of the ends from the terminal.

Spend time with your guinea pig everyday , etc, grooming, rubbing , ...and so on .

Does beta the magnet warrior appear in Yu-Gi-Oh The Duelists of the Roses?
Well you can get Beta the Magnet warrior along with Alpha and Gamma but I dont belive that they are in the game it's self.

He will usually start kissing you then rubbing your thigh with his hand or moving his hand along your side or along your neck. This could lead to more
Why does a magnet work under water?
Interesting question. The answer is maybe - it depends on the construction of the electromagnet. the key is the electromagnet must be water proof, and the wiring used to create the magnet must be insulated from water - if this is not done, then current will flow through the water, which will decay the effectiveness of the electromagnet, along with robbing it of strength due to a decrease in current through the magnet.

How can you keep a magnet safe?
Dont heat it or shake it a lot. if it gets de-magnetised (not a scientific term) just stroke another magnet along it to get all the particles facing the right way
