What do you mean by emf? What is meant by sound ranging? Give one use of sound ranging? What do we mean by dimension in the context of relativity? What does it mean by dimension in the context of relativity? In terms of physics, what does the term "graw" mean?
What does Wien's displacement law mean? What is the unit of measurement for displacement in the International System of Units? What is lateral shift? What actually torque is? What is resonance? What is hysteresis? What is permeability?
Definition. Lenz's law states that:The current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion. ... This means that the direction of the back EMF of an induced field opposes the...
What does high magnetic susceptibility mean? In electromagnetism, the magnetic susceptibility (Latin: susceptibilis, "receptive"; denoted χ) is ameasure of how much a material will become magnetized in an applied magnetic field. ... Magnetic susceptibility indicates whether a material is attracted ...
moon are in syzygy (alignment) in relation to the Earth. But that hasn't stopped humanity from givingunique names, such as "Buck Moon," to each full moon of the year, and that's why, once a decade or so, the world is treated to a super blue moon. But what does that even mean...
In 2016, Klaus Schwab, in an interview said something very strange. He said that within 10 years, by 2026, every single human being will be tagged with a digital identifier. What does that mean, and why? Let’s go through the sequence of events. A bioweapon is made with an antidote,...
Researchers have long criticized the SAR as an inadequate metric as it is measured in a mannequin – a liquid-filled phantom [19]. This does not capture the complex characteristics and interactions of living tissues' electromagnetic properties, or of RFR signals (e.g., the wave perturbations ne...
We believe that over hundreds of millions of years CO2levels have been decreasing dramatically in the Earth’s atmosphere. We also believe that over that time Earth’s temperature has been kept within a very narrow range compatible with life. So, a clear relationship between both does not exist...
Tags Mean Rms Root Signal Square In summary, the root mean squad (RMS) of a signal is important for electrical engineering because it is a type of average and it dissipates the same amount of heat in a resistor as the same DC voltage. Mar...
back EMF cannot be 180 degrees out of phase as @essenmein already said because that would mean that there would be a potential difference and the higher the potential difference (Voltage) between two points the higher the current so as back EMF would increase current would also increase, but...
