What is the thing that helps the needle move freely in a compass called?
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.
Why does a needle of a compass move when you put a bar of metal close to it?
The compass needle is a magnet and as you have probably tried, a magnet will 'stick' to an Iron bar. Thus as you move the compass near the Iron, its magnetic field lines are bent by the Iron and become locally stronger than the field lines of the planet, deflecting the needle away from north.
Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
In the first crude compass why was the needle floated in water?
Low friction so that weak magnet could move freely.
Why does a compass needle move when placed near a wire carrying an electric current?
True... The wire carring current creates a slight magnetic field.
When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
What happens to the compass needle when the circuit is shut off?
Yes it will show .It is because if electric current is passed through the wires then it will become an electromagnet and show magnetic properties.But there should be a circular coil in the circuit then only that part will show magnetic properties.

Why does the needle on a compass move when placed in the coil of wire?
It moves because it wants to have compass babies with raccoons and so it won't get high it move and that is it giving birth

Compass needle move when a current switched on?
this is because of magnetic field formed when the current flows through it. this is called electromagnetism. if we move the compass needle away from current carrying conductor or wire it returns to its position (north south position)

. The south magnetic pole of the compass points to Earth's north magnetic pole.
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 :)
Why can't visible light move a compass needle?
because light does not have any magnetic push/pull
How does a compass needle move when it is placed in a magnetic field?
A compass needle aligns itself with the magnetic field lines and points toward the magnetic north pole. The north-seeking end of the needle is attracted to the Earth's magnetic south pole, causing it to move and orient itself accordingly.
Which country did a man spot a compass needle move?
The country was Denmark - the physicist in question was Hans Christian Oersted
How did Oersted discover the relationship between an electricity and magnetism?
He used an electric current to affect the needle of a compass.
