Magnetic domain is defined as a group of atoms with magnetic fields.
A piece of iron can only become a magnet when the magnetic domain aligns.
Since we have an unmagnetized piece of iron, this means that its domain is not aligned. However, this does not mean that the domain does not exist.
Based on the above, the best choice would be:
There arr domains, but domains are oriented randomly.
Hope this helps :)
Velocity includes direction
It would go to the positive charge im like 99% sure of that
The answer is dark energy. This is the energy in the universe that opposes the gravitational attraction of matter in the universe. Initially, cosmologists had thought that the universe was decelerating due to the gravitational attraction between matter in the universe after the big bang. However, using the Doppler shift effect, evidence was gathered on the nature of the expansion of the universe.
