The needle on a compass normally points towards the Earth's magnetic north pole because it is magnetized and aligns itself with the Earth's magnetic field.
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.
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
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.
The north end of a compass needle would point toward the north pole of a bar magnet.
A needle on a compass is a magnet, and it aligns itself with the Earth's magnetic field. This allows the needle to point towards the magnetic North Pole. The movement of the needle is a result of the interaction between the Earth's magnetic field and the magnetic properties of the needle.
The needle, or "pointer", of a compass will always point North. See: http://en.wikipedia.org/wiki/Compass
What features of the earth makes a compass needle point north
the north pole
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.
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
To point to magnetic north.
It points to true north.
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 :)
If you point the north side of the compass away from you the compass will point south. Because the needle always points north (magnetism).
the compass's needle will point at the electromagnet
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.
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
