Answer 1

Hint: Each and every magnet has two poles that are a south pole and a north pole. The magnets experience repulsive and attractive forces. In a compass, the magnetic needle is used to find the direction. The magnet is used in building different closures.

Complete step-by-step solution:
A magnetic compass is the most familiar compass type. It works as a pointer to the magnetic north, which is the local magnetic meridian. As we know the magnetized needle aligns itself with the horizontal component of the earth’s magnetic field. The deflection of a compass needle due to local magnetic influences is called deviation.
The door of the cupboard is sometimes made up of magnets, as magnetic closures are commonly used to hold doors and drawers closed on everything. Usually, these closures are made with magnets and other parts like steel, plastic that makes a magnetic closure to the furniture.
Two objects that have like charges or like poles will repel each other. That is, the North Pole will exert a repulsive force on another north pole or a positive charge on another positive charge or negative charge on another negative charge when it comes in contact with each other. Therefore, the repulsive force will push the objects apart. Whereas, an attractive force is experienced when two, unlike charges or poles, come in contact with each other i.e., north-south pole or positive-negative charges.
The magnetic pole is the region at each end of a magnet where the external magnetic field is highest or strongest. A bar magnet suspended in Earth’s magnetic field Orients itself in a north-south direction.
Therefore, the correct matching will be A) with 4), B) with 3), C) with 2) and D) with 1).
Additional information: The first magnet was found from a naturally occurring mineral called magnetite. The magnetic compass was invented as a device for divination as early as the Chinese Han Dynasty in 206BC. Now it is used to find the direction.

Note: There are different types of magnets like a bar magnet, horseshoe magnet. A magnet consists of two poles north and south, or it has two charges positive and negative. A magnet experiences repulsive and attractive forces due to its charges and poles.
