Why does a compass move when it gets near an electromagnet?
When a compass gets near an electromagnet, the magnetic field produced by the electromagnet interferes with the Earth's magnetic field, causing the compass needle to align with the electromagnet's field instead. This phenomenon is known as magnetic deflection.
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.
True or false The device that turns a needle in a galvanometer is called an electromagnet.?
True. An electromagnet is used in a galvanometer to create a magnetic field that interacts with the current-carrying coil and causes the needle to move.
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 a needle on a compass move?
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.

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.
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)
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.
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.
