Amicroscopic magnetic region composed of a group of atoms whose magnetic fields are aligned in a common direction is called a(n in most materials, when these groups are randomly distributed, the substance will show magnetism.

A microscopic magnetic region composed of a group of atoms whose magnetic fields are aligned in a common direction is called as a DOMAIN. in most materials, when these groups are randomly distributed, the substance will show ZERO magnetism.

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second
