Instructables
Magnets.Almost everyone heard of it before .But how does it work? Does it only attract iron?Is its properties only attracting ferromagnetic elements?If not what are its uses?Is it easy to make a magnet?If possible, how?

In this instructable i will be trying to answer a few of  theses questions as easy as possible.It is a beginners guide for magnets.I know there are many experts of magnets on these website, so if I make any mistakes then help me correct,cause I am not at least professional. And i hope it will be a helpful guide for you.If any ideas about it, feel free to post, and if you like it it will be my pleasure.

If you like this you might want to see some more of my such projects and ideas on my profile on the link below  here: http://www.instructables.com/member/argha halder/

And most important some of the pictures used in the instructable is made by me,and others are taken from other websites,and i fully give them credit for the beautiful pictures.

Step 1: Basics of magnets

Picture of Basics of magnets
Every magnets have many properties some discovered ,some yet undiscovered.But some common basic properties every magnet has and we see are:
1) Every magnet has two poles.The two ends of a magnet are its two poles and these are north and south.The magnetic fields of magnets are highest at its two poles, and if a magnet is broken into half or smaller or any size the ends of the new broken pieces are also the two poles. So if a magnet having two poles broken int two pieces then the newly produced magnets will have two poles each.
2)The opposite poles of two magnets attract each other.And the same poles of two magnets repel each other.
3)Magnetic force affect most of the substances,but the effect is more in some materials and less in some material.
4)Magnets attract ferromagnetic materials like iron,steel,cobalt,nickel etc.
5)If magnets are moved in between a coil of wire it produces electricity .
Is there a material that can deviate/ prevent/ reflect magnetic lines from another magnet without interacting with it?

Sorry wrong window. Anyway what happens if you pass a current through a magnet?

Your question is a big one and is a very good one. My answer to you is extensive but if you are patient you can learn a very fascinating journey.
It all depends on how much current you pump through a magnet and whether or not the magnet is fixed or allowed to move, as well as the duration of the current. If you have a small current and you push it momentarily through the magnet while it is loose and mobile it can do one of two things. In a dc current you can get the magnet to align with the direction of the current. There is a very famous experiment where a scientist by the name of Hans Christian Oersted. He actually made a mistake at the beginning of his experiment and when his assistant noticed there was a little charge left in the battery they retried it with the wire at a different angle and discovered that the magnet moves. For more info you can click on this link http://en.wikipedia.org/wiki/Hans_Christian_%C3%98rsted
If you push a lot of current into a magnet you will damage the magnet causing it to depolarize and be just a lump of metal. If you force a huge current through a magnet you can cause it to melt. All of this is dependent on whether you are using ac or dc as well. Ac will cause a magnet to jump around. This is the principle of certain magnetic motors but again Ac will depolarize a magnet. There is certain magnet motors that are ac but they have circuitry to keep them from hurting the motor. Dc motors are magnet motors and this is the driving force for them.
Again the question you asked has a detailed answer and there have been whole books written on your question. I hope I have answered your question as much as i could in this limited space without boring you to death though. And keep up the good questions. Learning is always a worthy endeavor.
