Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A group of atoms that has all like poles pointing in the same direction are called
A
magnetic forces.
B
magnetic fields.
C
magnetic domains.
D
magnetic poles.
Explanation: 

Detailed explanation-1: -A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

Detailed explanation-2: -A magnetic domain is a group of atoms with their poles aligned in the same direction. In permanent magnets, the magnetic domains are aligned with each other to produce a net magnetic force. Some materials can become temporary magnets.

Detailed explanation-3: -Groups of atoms with aligned magnetic poles are called magnetic domains. Each domain contains an enormous number of atoms, yet the domains are too small to be seen with the unaided eye.

Detailed explanation-4: -In ferromagnetic materials, the atoms form structures called domains. A domain is a region inside of a material where groups of magnetic moments naturally align in the same direction.

Detailed explanation-5: -Each atom has its own magnetic field, and if a group of atoms can align their magnetic fields, this group or cluster of atoms is called a magnetic domain.
