What else can I help you with?
Determine the direction in which a compass needle will point when held above a wire with positive charges moving west?
The compass needle will point towards the wire, perpendicular to the current flow. Since the positive charges are moving west, the magnetic field generated by their movement will induce a force on the compass needle causing it to point towards the wire.
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.
When a current flows from east to west what direction will a compass point to?
A compass needle aligns with the Earth's magnetic field, which typically points north. In this scenario, with a current flowing from east to west, the compass needle will still point north. The direction of current flow does not affect the orientation of the compass needle.
Which end of a compass needle would point toward the north pole of a bar magnet?
The north end of a compass needle would point toward the north pole of a bar magnet.
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.
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 feature of the Earth makes a compass needle point north?
What features of the earth makes a compass needle point north
What does a needle in a compass point to?
the north pole

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 an navigational tool with a needle?
A navigational tool with a needle is a compass because it helps you to navigate which is cosidered as a tool. A compass has a needle inside to point which way is north. There is your answer :)
What is the compass needle used for?
To point to magnetic north.
What does a compass needle point do?
It points to true north.
Where will a compass point if you face south?
If you point the north side of the compass away from you the compass will point south. Because the needle always points north (magnetism).
What will happen if you put a compass next to an electromagnet that is switched?
the compass's needle will point at the electromagnet
When a current flows from east to west what direction will a compass point to?
A compass needle aligns with the Earth's magnetic field, which typically points north. In this scenario, with a current flowing from east to west, the compass needle will still point north. The direction of current flow does not affect the orientation of the compass needle.
Is A compass needle permanent a magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
