HYSTERESIS CURVE
What is Hysteresis?
Hysteresis is the time-based dependence of a system 's output on present and past inputs. It is applied to almost any phenomenon that cycles with a lag time between. Hysteresis occurs in ferromagnetic and ferroelectric materials, also in the deformation of rubber bands and shape-memory alloys and many other natural phenomena.
What is hysteresis curve?
A hysteresis curve is a chart-form for hysteresis. In magnetic hysteresis, magnetizing doesn’t happen immediately nor does demagnetizing, there always is a gradual lag both ways. Technically, the hysteresis curve shows a relationship between the induced flux density and magnetizing force. The loop is generated by measuring the magnetic flux of a ferromagnetic material while the magnetizing force is changed. A ferromagnetic material that has not been previously magnetized or has been demagnetized will follow the dashed line as H is increased. …show more content…

Geothermal energy heats hot springs at the earth 's surface, which have long been used by humans. More recently, people have used geothermal energy for electricity generation by tapping into underground steam reservoirs. The greatest advantage of geothermal energy use is that it tends to be cleaner than other energy sources. It can also be considered a renewable resource. However, it is possible to use up water resources faster than they can naturally be replenished. The greatest disadvantage to geothermal energy use is that it is only readily available in volcanic

  • The Naica Mine: The Cave Of Crystals

    This cave is located 1000 feet underground and contains many of the largest natural gypsum crystals in the world (2). These pillars of selenite gypsum measure up to 50 feet long and 4 feet in diameter (1). These crystals were able to form in such huge quantities because the area was submerged in water that was rich in minerals as well as having a high stable temperature of 136 degrees Fahrenheit (2). The water had an abundant amount of anhydrite and, because of this environment, it dissolved into gypsum and formed these massive crystals (2). The water has since drained out of the caves and the air in the caves normally stays between 45 and 50 degrees Celsius and the humidity levels range from 90 to 100 percent (3).

    Usually, the Federal Reserve is going to do this when the country’s economy is flat lining or contracting and this is the Federal Reserves response in order to try and stimulate growth. (Cecchetti) Thus, the flat yield curve is a good indicator that the economy is full of uncertainty and will most likely slow down or could potentially go into a recession. (The Board of Governors of the Federal Reserve) An inverted or downward sloping yield curve says that economists believe the Federal Reserve is going to cut interest or slash interest rates significantly.

  • Hypnosis External Causes

    1370 Words  | 6 Pages

    For example, in the case of levitating hands under hypnosis, subjects describe that they do not have the feeling of moving hands, but their hand moves upward. People who have experienced reluctance have the idea that their hand will do so in accordance with their actions, and before doing so they have a problem with differentiating whether they think the sole cause of the act. In everyday situations, the person has a very clear and well-trained idea for upcoming events, so the idea of the action is formed as an expectation rather than a purpose. In hypnosis, intentions are happening before the action and because of this there is a lack of experience of will. Such a conscious will is lacking, even when knowledge of action is present.

    Benefits of Grounding I. Grounding is a way of reconnecting to the earthing energy. Also is a good reminder that we all need the earth to survive and that we eat from the earth. What grounding does in that process of walking barefoot on the ground is it gives the free electrons from the earth and brings it to the body and the surface of the red blood cells. The health benefits of daily grounding include decreasing stress, strengthening and stretching in muscles, while also decreasing anxiety and depression.

  • Non Renewable Resources Essay

    2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
