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

Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.


What is a magnetic compass?

A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

How does a magnetized needle work?

The magnetic field of earth exerts a torque on the needle, pulling one end or pole of the needle toward the Earth's North magnetic pole, and the other toward the South magnetic. The needle is mounted on a low-friction pivot point, in better magnetized needle a jewel bearing, so it can turn easily. When the magnetized needle is held level, the needle turns until, after a few seconds to allow oscillations to die out, one end points toward the North magnetic pole.


How does a compass needle respond when a compass needle is placed within a magnetic field?

A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.


Does a compass needle line up perpendicular or parallel to a magnetic field?

A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.


How does a compass needle respond when a compass is placed in a magnetic field?

If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions

What happens to the compass needle when you place it in the wire loop when the circuit was turn on?

it point same way as magnetic field


How does a compass needle align itself?

A compass has a needle that is magnetized. This needle is suspended so that it can rotate freely and it can align itself with any magnetic field it is exposed to.If you put a magnet close to a compass, the needle will align itself with the magnets magnetic field.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.
