How Permanent Magnet is Made


Quote by lasily View Post
A permanent magnet is the one whose electronic domains are aligned in a particular direction as opposed to the iron in which they are scattered and multi-directional. To make a permanent magnet, you can induce magnetism by keepin in close proximity to a magnetic bar or in a magnetic field.

An electromagnet is the one in which magnetic power is induced through electricity. They find applications in generators. Normal magnets do not need any electricity for their magnetism.
What is meant by Electronic Domains ????

Have you read anything at this level yet?

or this?

Why do you keep picking one phrase from an answer that you get and, again ask "what is ....?"? Why not google the term and read a few of the links it throws up? Seriously, it gives the impression that you are making no effort for yourself at all.

If you want to have a worthwhile conversation on PF, the best way is to go and find two or three pieces of information elsewhere that seem to contradict or where you can't see the connection and then ask for opinions here. It makes answering worth while for other members.

What is the direction of Earth magnetic force ?? Vertically Or Horizontally ??
You mean direction of the field lines, not force. There is no force when you are talking about a single object, force is between two objects, and the direction of the force is along the shortest distance between the two, more or less depending on the shape and distribution of the fields.

If Earth's North pole And Magnet North pole can repel each other, then why does not the magnet become suspended in the air due to it's own and earth repulsion force... ?????

Try suspending the planet above a magnet! You just need suitable strong magnet..

Why don't try thinking (in conjunction with reading around) instead of asking?
