From an Engineering standpoint, it is called a BEARING. In a cheap compass it is a simple PINPOINT in the Base, and a CUP on the bottom of the Needle.

How does a compass work using the Earth's magnetic field?
a compass has a magnetic point which points to the north pole. well yes but....a compass has a magnetic needle inside it which attracts it self to the earths magnetic field. it may not actually point to the norht pole but actually to the earths magnetic north pole
Which part of metallic bonding theory helps the most to explain why metals are able to conduct electricity?
Electrons can move freely among all the atoms of the metal.
What is oersted's law?
If you want it in simply words, then it is like this. Scientist Oersted found out that when electricity passes through a wire, it produces magnetism. If you search about Oersted Law in google, you only get the apparatus. Try it and you can find the result. He actually found out this phenomena when he was doing a bit of research after his lecture in his colledge. He was also the person to obtain aluminiun for the first time ever.

What is an navigational tool with a needle?
A navigational tool with a needle is a compass because it helps you to navigate which is cosidered as a tool. A compass has a needle inside to point which way is north. There is your answer :)
What is the circuit's total resistance?
You take the wire(s) that are in the circuit and place it on on a compass. Hold the compass still and the needle in the compass will move. However far that the needle is turned will detrmine how much resistance is in the circuit. (You know you have done this correctly if the needle in the compass spins counter clockwise.) Hope this helps you out :)
Who discovered the elctromagnetism?
Electromagnetism was discovered by Hans Christian Orsted, a danish scientist in 1820. Whilst preparing for a lecture, he noticed that a compass needle could be moved by the electric current in a battery. Hope that helps!! x
Why does the compass help us today?

How do you find the shape of a magnetic field using a compass?
Yes. I can be done using iron filings and a clear piece of plastic. Pour on the iron filings, put on the plastic, and then the magnet. The iron filings should form the shape of the magnetic field around it. If that does not work, here is a link to a picture... http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg Hope that helps.
What is the measurement of a needle?
use a ruler. that helps.
Why doesn't some substances conduct electricity?
To conduct electricity you need the ability for tiny particles called electrons to move freely from one atom or molecule to another. If there are no electrons moving freely, there is no electrical charge. :) hope this helps
