The needle in a compass points towards a magnetic pole . Earth’s north magnetic pole is actually the South Pole of earth’s geographic poles and vice – versa. Hence, a freely suspended magnetic needlepoint in a geographic north-south direction. The magnetic compass is the device that uses this principle.
Why does a freely suspended magnetic needle align itself in the geographic north-south direction?
Magnetism | Short/Long Answer Questions
A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
Why does a suspended compass needle stay in north-south direction?
When a magnetic needle is suspended such that it is free to rotate in a horizontal plane, it always rests indicating the geographic north-south direction. It is clear that the north pole of a magnet will point towards the geographic north only when there is a magnetic south pole attracting it.
Why magnetic needle always points towards north-south direction on which property of magnet magnetic needle work?
A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth’s built-in magnet . ... Now if the needle in your compass is pointing north, that means it’s being attracted (pulled toward) something near Earth’s north pole.
In which direction does a freely suspended compass needle align itself?
When a Magnetic needle is suspended freely, it always aligns itself in the direction of the magnetic north-pole and south-pole of the earth , the north pole of the needle gets attracted towards the magnetic south pole of the earth and the south gets repelled equally away from it.
Where will be a freely suspended magnet perfectly horizontal?
Direction of earth’s magnetic field is from S (geographical south) to N (geographical north). Therefore, when a magnet is freely suspended, it rests in the geographic north-south direction .
In which direction does a freely suspended magnet settle?
Magnet consist of two poles south pole and north pole. we know that earth itself behave like a magnet. so, when magnet is suspended freely then its north pole gets attracted towards the south of the earth. Hence magnet always settle in the North-South direction of earth.
Why does a compass always point to the north direction?
The magnetic field is a zone where the force is active along imaginary lines. From the south magnetic pole to the north magnetic pole, this force has an effect on all magnetized objects, such as the needle of a compass. Under the effect of Earth’s magnetic field , the needle always points toward the north magnetic pole.
Why does magnet always point to north?
Earth’s south magnetic pole is near Earth’s geographic north. Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a compass points toward north because that’s where Earth’s south magnetic pole is located and they attract.
Which direction do magnetic needles show?
The magnetic pole of a compass needle is defined to be the “ north-seeking” end , i.e., the end that “seeks” (points generally toward) the north geographic pole. Magnetic field of the earth (idealized). Arrows show the direction a compass points.
What are the 4 major properties of magnet?
- Magnets will attract ferromagnetic substances.
- Like poles of the magnet repel each other and unlike poles attract each other.
- A suspended magnet always comes to rest in the north-south direction.
- The poles of the magnet are in pairs.
What will happen if we bring a magnet near a compass?
If a compass is brought near a magnet its needle gets deflected due to the magnetic field of magnet . If a compass is brought near a magnet its needle gets deflected due to the magnetic field of magnet.
What is the direction of the magnetic lines of force outside the magnet?
Magnetic lines of force are closed curves. C) Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole.
Does a compass point to geographic North Pole?
Magnets, Compasses and North Bearings
The Geographic North Pole is where lines of longitudes converge into what we call the North Pole. The Magnetic Pole is a point in Northern Canada where the northern lines of attraction enter the Earth. A compass needle will point to the direction of the Magnetic North Pole .
Where the strength of magnet is maximum?
Where on a magnet is the magnetic pull the strongest? The magnetic field generated by any magnet is always strongest at either pole . The magnetic force is equally as strong at both the north and south pole.
In which direction would a compass needle align?
Compass needles are designed to align with Earth’s magnetic field, with the north end of the needle pointing to the magnetic North Pole and the opposite end of the needle pointing to the magnetic South Pole.
