Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Surrounding every magnet is a ____ ____
A
magnetic field
B
electrical current
C
another magnet
D
None of the above
Explanation: 

Detailed explanation-1: -The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles . Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction.

Detailed explanation-2: -Every magnet is surrounded by an invisible force field of lines with pulling and pushing power called a magnetic field. All magnets have two poles: a north-seeking or north pole, and a south-seeking or south pole. Opposite poles attract and like poles repel each other.

Detailed explanation-3: -The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force.

Detailed explanation-4: -Space surrounding a magnet in which magnetic force is executed, is called a magnetic field. A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials.

Detailed explanation-5: -Every magnet is surrounded by an invisible, three-dimensional magnetic field. A field is a region in which something varies from point to point. In Earth’s atmosphere, for example, wind speed and direction vary from place to place.
