Why is a nail attracted to a magnet?
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
How could magnetic rocks affect a compass and why?
In a regular magnetic compass, the needle is a magnet. One end is the south pole and the other end is the north pole. Magnets are affected by other magnets. If a magnet is placed near a magnetic compass, the north pole of the compass's needle is attracted by the south pole of the magnet, and the south pole of the compass's needle is attracted by the north pole of the magnet.
On a bar magnet where are lines of magnetic force the greatest?
near both magnetic poles
Why do you think compass might not work near storm power lines?
Compasses do not work well in the presence of of electromagnetic fields.
Why do magnetic compasses giver false reading?
Because compasses have better things to do.
What do you call that is when they are brought near each other they will repel?
magnetic force
Use magnetic field in a sentence?
Magnetic compasses will become unuseful when near a magnetic field.
When placed near each other opposites magnetic poles repel each other?
Yes, Because they repel each other.
When placed near each other opposite magnetic poles repel each other.?
Yes, Because they repel each other.
Why compass point towards north?
The compass has a small magnet, that can move around freely. This is affected by the Earth's magnetic field. The Earth's magnetic south pole is near its geographic northpole, but not exactly so.
What two south magnetic poles brought near each other?
Two south (or two north) magnetic poles will repel each other. A south and north pole will attract each other.
When a compass pointing north will point in a different direction when placed near a piece of metal Which causes this to happen?
The needle in compasses is magnetic and is drawn to the Earth's magneticism in the North. When the needle is placed near a metal, as all magnets are, attracted to metals.
How do you use repel in a sentence?
This new product is designed to repel mosquitoes before they get anywhere near you.

Do compasses always point toward geographic south?
No. A compass, being at its heart a magnet, is attuned to Earth's magnetic north, which is currently near Canada's Ellesmere Island, and moving in the direction of Russia at approximately 40 miles (65 km.) per year.For most purposes, the geographic and magnetic north poles are close enough to make little difference; but as you approach one or the other, you have to use a conversion chart to find your true location.

If a magnet is placed near a magnetic compass, the north pole of the compass's needle is attracted by the south pole of the magnet, and the south pole of the compass's needle is attracted by the north pole of the magnet.
What happens when a magnetic compass is held in space far away from earth's magnetic field....will it be influenced by the other stellar objects which may or may not have magnetic poles of their own?
How far away? Compasses function based on their interaction with the Earth's magnetic field. If a person were to take a compass outside of that field, it would cease to provide any relevant information. Of course, no human has ever been anywhere near that far away, but interplanetary robots and probes have.
