How does an inducted magnetic field influence the direction of a compass needle?
The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
What does a magnetic compass do?
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
How yo find the magnetic field of earth at a particular place?
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
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.
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
How does a compass act to the relation to earth?
A magnetic compass acts in relation to the Earth by aligning a magnetised needle with the lines of the Earth's magnetic field; thus resulting in a needle which points to magnetic North.
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.
Which pole of a compass magnet is attracted to Earth's magnetic north pole?
The pole of the compass that is attracted to the earth's magnetic north pole must be a south magnetic pole. But here's the thing. In the compass, the south magnetic pole of the needle is marked "N" because that end of the compass needle points to earth's magnetic north. The only way the needle can point to earth's magnetic north is if that end of the needle, the one marked with an "N" on it, is a magnetic south pole. It almost seems counter intuitive, but think it through and it will become clear.

What magnetized steel needle that aligns with the magnetic of the earth is a?
compass
Why a magnetic needle comes to rest the north south position?
The compass needle is attracted by the Earth's magnetic field.
What causes a compass needle to align with the Earth's North and South poles?
The compass needle aligns to the Earth's magnetic field. This magnetic field is not exactly aligned with the Earth's rotation, but the magnetic south pole is close enough to the geographic north pole for the compass to be useful in most places.

What is a magnetized needle that is attracted to the Earth's North magnetic pole?
It is still a needle, but could be referred to as a 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.
