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.
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 direction does the magnetic needle of a compass point to?
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
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.
What must be done first to an ordinary sewing needle to make it a compass needle?
To make an ordinary sewing needle into a compass needle, it must first be demagnetized by heating it to a high temperature and then allowing it to cool in a specific orientation. This aligns the needle's magnetic domains and makes it a more effective compass needle.
What is the name of the line with which a compass aligns?

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
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
What is the moveable bar in a compass called?
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
