A needle on a compass is a magnet, and it aligns itself with the Earth's magnetic field. This allows the needle to point towards the magnetic North Pole. The movement of the needle is a result of the interaction between the Earth's magnetic field and the magnetic properties of the needle.
What else can I help you with?
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.
What is the thing that helps the needle move freely in a compass called?
The thing that helps the needle move freely in a compass is called a pivot or bearing. It is usually a low-friction point that allows the needle to align with the Earth's magnetic field and point north.
Why does an compass needle move when it is brought near an electromagnet?
A compass needle is a tiny magnet that aligns with the magnetic field around it. When brought near an electromagnet, the magnetic field produced by the electromagnet affects the compass needle, causing it to align with the new magnetic field created by the electromagnet.
What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
What happens to the needle of a compass as a wire carrying electric current is placed across it?
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
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.
Why can't visible light move a compass needle?
Visible light can't move a compass needle because light consists of electromagnetic waves, while a compass needle is affected by the Earth's magnetic field. The magnetic field from visible light is not strong enough to influence the orientation of a compass needle.

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)
What is the magnet in a compass?
The compass needle.

The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
What Caused the compass needle to move?
A compass needle moves because it aligns itself with the Earth's magnetic field, which is generated by the movement of molten iron in the outer core of the Earth. This causes the needle to point towards the Earth's magnetic North 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 :)
