How Permanent Magnet is Made

Some 'English Pedantry' here. The thing you draw circles with is officially called a 'Pair of Compasses'. No idea why but the two things do actually have different names.

I am beginning to wonder just how much reading Xidike is doing. This stuff is described all over the Web at many different levels - and not only in English, I'm sure.

Find out what a compass is made of.

Xidike

The Compass I have, I don't know of which material it is made of.. But when I take my magnet near to it,, it does not attract the magnet,, but the needle of compass is affected by the magnet..

You are still asking questions about stuff you could have easily found out for yourself. I did a quick search and, amongst an avalanche of useful sites, I found this one which has answers to all of your questions, afaics. HERE. Please read this thoroughly before asking any more questions.

Thanks Man... That was a great article.. It increased my knowledge a lot about magnetism.. But I still Can't find my answer.. that how compass tell the direction of North And South Pole Of Earth And Magnet..

Drakkith

Opposite poles attract. What does that tell you about a compass needle?

sophiecentaur

What about the diagram of magnetic field lines? Isn't that clear enough? I don't think you read carefully enough. The small compass needle lays along the lines.

Xidike

I know that like poles repel each other and opposite attract each other..
Answer of my question was not there

I am beginning to question your motives for posting on PF. Are you just trying to wind people up? (It's working, I think)

Xidike

How compass detect the Earth’s natural magnetic fields, to tell the direction ??

Drakkith

The same way two magnets detect each other.

sophiecentaur

If you won't read that link fully then I don't think you will read any answer I give you. No more spoonfeeding. I'm done.

Xidike

Then why the north pole of Earth and north pole of Magnet Does not repel each other.. ????

Drakkith

Because the North pole of the Earth is actually a magnetic SOUTH pole!!!
(I'm serious)
I think that poles of magnets were named a certain way because one pole wanted to face North all the time. This requires that the other pole, the Earth's pole, be a south pole. I'd bet that way back in the day when magnetism was first studied, they noticed that one pole wanted to face North all the time so they labeled the Earth's pole a NORTH pole since it was in the North, and ignored the fact that the Magnetic pole was actually a magnetic SOUTH pole.

Ahhh. I see your problem and the confusion. The following can be found on the net - I have read it but people don't always bother to make it clear. It confused me at School when I was first taught about magnets. I think many people don't even worry about it at all.

The Correct Name for the 'North Pole' that is marked a magnet is actually a 'North Seeking Pole'. This means it will point to the Earth's North Pole. So this means (annoyingly and confusingly!!!) that, at the Earth's North Pole, there must be a South Seeking Pole - because that will follow the attraction / repulsion rules for magnets in general!

Is there any condition when Earth And Magnet Repel Each others ??
