Question

The figure shows a magnetic compass. What will happen to the position of its needle if you bring a bar magnet near it?

Answer 1

Hint: In navigation or surveying, a magnetic compass is a device that uses a magnetic marker to determine position on the Earth's surface by aligning itself with the magnetic field. The magnetic compass is the oldest and most well-known form of compass, and it is used in a variety of ways by surveyors and in aircraft, ships, and ground vehicles.

Complete answer:
A bar magnet is a rectangular fragment of an object that has permanent magnetic properties and is made of iron, steel, or some other ferromagnetic material or ferromagnetic composite. It has two poles, one north and one south, and when suspended freely, the magnet aligns itself so that the northern pole faces the earth's magnetic north pole.Rectangular bar magnets are used in manufacturing and engineering because they have a higher magnetic strength and field than most magnets.

Needle of the magnetic compass is deflected when a bar magnet is brought up to a magnetic compass. As the north pole of the magnet is brought close to the compass, the needle's south side is drawn to it. As the south pole of the magnet is brought up to the compass, the needle's north side is drawn to it.

Note:Normal and artificial magnets are divided into two categories depending on how they acquired their magnetism, how long they maintain their magnetic abilities, and their magnetic field. Natural magnets are much smaller than artificial magnets and can be found in nature. Natural magnets have a mild magnetic field and are used in nature. Natural magnets are commonly found in lodestones. Artificial magnets have a greater magnetic field which can be generated by man-made means. They can also be moulded to suit your needs.A bar magnet is an artificial magnet that has been moulded into a bar shape.
