What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
What is the magnet in a compass?
The compass needle.
An electric current cannot be used to deflect a compass needle?
An electric current can be used to deflect a compass needle. When an electric current flows through a conductor, it generates a magnetic field around it, which can interact with the magnetic field of the compass needle, causing it to deflect. This principle is the basis for electromagnetism.
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.
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.
Why is LED on compass needle used in tester sometime?
LEDs are used in some compass testers to provide a visual indication when the compass needle is aligned with the Earth's magnetic field. When the needle points north, it completes an electrical circuit that activates the LED, serving as a simple and effective way to confirm correct calibration.
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
How does a compass needle respond when a compass is placed with 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 a compass needle be made from?
Answer:A compass needle can be made from any ferrous metal that can be magnetized.
Is it possible to use compass needle at the poles?
Yes it is possible to use compass needle at the poles
Infer what characteristic of a compass needle accounts for your observation of the compass and the magnet?
The characteristic of magnetism in the compass needle allows it to align itself with the Earth's magnetic field, indicating the North and South poles. This alignment enables the compass needle to point towards the magnetic North pole of the Earth when used with a magnet.
Which way does a compass needle usually point?
The needle, or "pointer", of a compass will always point North. See: http://en.wikipedia.org/wiki/Compass
