What is the difference between para-magnetism and ferro-magnetism?
Paramagnetism refers to materials like aluminum or platinum which become magnetized in a magnetic field but their magnetism disappears when the field is removed. Ferromagnetism refers to materials (such as iron and nickel) that can retain their magnetic properties when the magnetic field is removed and kifjkjf
What does the term ferromagnetic mean?
a ferromagnetic is of or relating to substances with an abnormally high magnet permeability, a definite saturation point, and appreciable residal magnetism and hysteresis.
How does saturation affect solubility?
Temperature affects the saturation point (:
Reverse saturation current of Ge diode?
Reverse saturation current of germanium diodeThe current that exists under reverse bias conditions is called the reverse saturation current. Reverse saturation current of the germanium diode is typically 1 micro ampere or 10-6 a.At a fixed temperature, the reverse saturation current of a diode increases with increase in applied reverse bias. In reverse bias region the reverse saturation current also varies with the temperature.
What is true of any ferromagnetic materials?
It has an abnormally high magnetic permeability, it has a definite saturation point, and it has appreciable residual magnetism and hysteresis. That's why it remains magnetic even after the forcing magnetic field goes away.
What would happen to the saturation in oxygen when its hot?
I'm assuming you're referring to saturation of oxygen in the blood. If the temperature is increased, oxyhemoglobin curve is shifted to the right, meaning hemoglobin realeses oxygen more readily, thus increasing blood oxygen saturation.
What is saturation temperature of steam?
Saturation temperature of steam is the Temperature at whihc any addition of heat does not increase the temperature of the water but produces steam.It depends upon the pressue and for every pressure there is a saturation temperature.

At what location in a refrigeration system does the Saturation pressure correspond with the saturation temperature?
Compressor and evaporator
What is the difference between pinch point and approach temperature?
Both temperatures are related to the saturation temperature in the steam drum of a heat recovery steam generator. The approach temperature is the water temperature at the economizer outlet, which in many analyses is assumed to be equal to the saturation temperature for simplicity. The "pinch point temperature difference" is the difference between the saturation temperature and the gas temperature at the economizer inlet.
What is the difference between dry steam and wet steam to clean?
DRY steam is superheated There is a temperature below which steam will start to condense into water droplets. This is called the saturation temperature, and it varies with the pressure of the steam. Steam that is exactly at its saturation temperature is called saturated steam. Steam that is below its saturation temperature contains droplets of moisture and is called wet steam. Steam that is above its saturation temperature is called superheated steam.

Classification of magnetic materials?
The magnetic behavior of materials can be classified into the following five major groups:1. Diamagnetism2. Paramagnetism3. Ferromagnetism4. Ferrimagnetism5. AntiferromagnetismMagnetic Properties of some common mineralsMaterials in the first two groups are those that exhibit no collective magnetic interactions and are not magnetically ordered. Materials in the last three groups exhibit long-range magnetic order below a certain critical temperature. Ferromagnetic and ferrimagnetic materials are usually what we consider as being magnetic (ie., behaving like iron). The remaining three are so weakly magnetic that they are usually thought of as "nonmagnetic".1. DiamagnetismDiamagnetism is a fundamental property of all matter, although it is usually very weak. It is due to the non-cooperative behavior of orbiting electrons when exposed to an applied magnetic field. Diamagnetic substances are composed of atoms which have no net magnetic moments (ie., all the orbital shells are filled and there are no unpaired electrons). However, when exposed to a field, a negative magnetization is produced and thus the susceptibility is negative. If we plot M vs H, we see:Note that when the field is zero the magnetization is zero. The other characteristic behavior of diamagnetic materials is that the susceptibility is temperature independent. Some well known diamagnetic substances, in units of 10-8 m3/kg, include:quartz (SiO2) -0.62Calcite (CaCO3) -0.48water -0.90TOP2. ParamagnetismThis class of materials, some of the atoms or ions in the material have a net magnetic moment due to unpaired electrons in partially filled orbitals. One of the most important atoms with unpaired electrons is iron. However, the individual magnetic moments do not interact magnetically, and like diamagnetism, the magnetization is zero when the field is removed. In the presence of a field, there is now a partial alignment of the atomic magnetic moments in the direction of the field, resulting in a net positive magnetization and positive susceptibility.In addition, the efficiency of the field in aligning the moments is opposed by the randomizing effects of temperature. This results in a temperature dependent susceptibility, known as the Curie Law.At normal temperatures and in moderate fields, the paramagnetic susceptibility is small (but larger than the diamagnetic contribution). Unless the temperature is very low (
How does the relative permeability of a ferromagnetic material vary with magnetomotive force?
There are a lot of subtle things associated with the answer to this question, but it might be best to answer by saying that with increasing magneto-motive force (MMF), the permeability of the material doesn't really change that much until the magnetic saturation of the material is approached.
