Remans are native to the planet Remus. They have been subjugated ever since the Romulans staked claim and set up their new homeworld in the system. Since Remus is tidally locked with the system's primary star, the species is in constant darkness, and so the Remans are extremely sensitive to light.
The Remans were treated as second class citizens within the Romulan Empire. Remus is a prime planet of dilithium mining and as such many Remans are forced into slave labour. As a result of the Remans' subjugation and harsh treatment, the Romulan Senate and the Praetor were killed in an conspiracy led by Shinzon (Star Trek: Nemesis) to gain control of the Empire and use his new starship, the Scimitar, equipped with thalaron weapons and a nearly impenetrable cloak, to destroy every lifeform on Earth. It is also known that Remans were used by Romulans as shock troops during the Dominion War.
Whereas the unrolled, unloaded sample possess a remanence in the range of 35% of saturation, the rolled, unloaded sample has a remanence in the range of 2 to 3% of saturation depending on the maximum field applied.
1, the remanence to saturation magnetization ratio is plotted against increasing load for the sample prior to rolling, and for the rolled sample with three different fields impressed thereon.
It may be seen that in all cases, the rolling has substantially reduced the unloaded remanence, but that the impressed magnetic field tends to push the remanence back upwardly toward that of the sample prior to rolling.
