A compass needle changes direction because it aligns itself with the magnetic field of the Earth. The Earth's magnetic field is generated by the movement of molten iron in its outer core. This causes the needle to point towards magnetic north.

A compass needle changes direction if the flow of electricity in the wire near it is reversed?

Yes, when the flow of electricity in a wire near a compass needle is reversed, the magnetic field generated by the current also changes direction. This change in magnetic field influences the orientation of the compass needle, causing it to change direction accordingly.


Does the compass needle change direction if the flow of electricity in the wire near it is reversed?

Yes, the compass needle will change direction if the flow of electricity in the wire near it is reversed. This is because the flow of electricity creates a magnetic field around the wire, which can interact with the magnetic field of the compass needle.


Why does a compass needle change direction when it is near a magnetic field?

A compass needle is a small magnet that aligns itself with the Earth's magnetic field. When near a stronger magnetic field, like that of a magnet, the compass needle will be influenced by the stronger field and adjust its direction to align with it.


How compass changes direction?

A compass needle aligns itself with the Earth's magnetic field, pointing towards the magnetic North Pole. When the compass is moved or rotated, the needle remains aligned with the magnetic field, causing it to change direction accordingly.


Why would lightning storms change the direction of a ships compass needle?

Lightning can create a strong magnetic field when it strikes a ship, causing the ship's compass needle to temporarily change direction. The intense electromagnetic field generated by the lightning can interfere with the magnetic field that the compass relies on for navigation. Once the lightning subsides, the compass should return to its normal direction.

How could you change the direction in which a compass needle points using a cell and a piece of wire?

You can change the direction of a compass needle by creating a magnetic field with a current-carrying wire. By passing a current through the wire and holding it near the compass needle, you can influence the direction in which the needle points. The strength and orientation of the magnetic field generated by the wire can cause the compass needle to deflect from its original direction.


What is the effect on the direction of the compass needle when you close the circuit?

When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.


Why does a compass change direction when a metal is near?

When a metal object is brought near a compass, it can disrupt the Earth's magnetic field around the compass. This disruption causes the compass needle to align itself with the new magnetic field created by the metal object, resulting in a change in direction.


Is a compass needle a transformer?

No, a compass needle is not a transformer. A compass needle is a simple magnetic instrument that aligns itself with the Earth's magnetic field to show the direction of North. Transformers, on the other hand, are devices used to change the voltage and current levels in electrical circuits.


What is the name of the force that changes direction of a compass needle?

The force that changes the direction of a compass needle is called the magnetic force, which is generated by the Earth's magnetic field.


How far do you need to keep a magnet from a compass?

To avoid interference, keep a magnet at least 15 cm (6 inches) away from a compass. This distance prevents the magnet from affecting the compass needle's orientation.


What direction does the magnetic needle of a compass point to?

The magnetic needle of a compass points towards the Earth's magnetic North Pole.
