Tcoef of Bris the temperature coefficient of Br in terms of % per degree Centigrade. This tells you how the magnetic flux changes with respect to temperature. -0.20 means that if the temperature increases by 100 degrees Centigrade, its magnetic flux will decrease by 20%!
In some cases, CBP may appear as a bright portion of a larger loop (with clearly identifiable footpoints), and in some cases, an isolated CBP may develop between magnetic poles, which might not be the closest ones to each other or which might not be involved in the magnetic flux ...
The permeability of free space is a special constant that tells us the magnetic permeability in a vacuum or empty space. This dimensionless quantity is generally represented by \mu_{0} (pronounced as mu zero or mu naught). What do you mean by magnetic permeability? Magnetic permeability is a...
This tells you how the magnetic flux changes with respect to temperature. -0.20 means that if the temperature increases by 100 degrees Centigrade, its magnetic flux will decrease by 20%! Tmax is the maximum temperature the magnet should be operated at. After the temperature drops below this ...

One of the laws discovered by Kepler relates the radius of orbit with period, namely, the time taken to complete an orbit.fn5 We know the radius of the orbit of the real Moon (Hipparchus had measured it in antiquity) and its period (one month). We know the radius of the orbit of th...

Parrington also tells an evolutionary tale, but his aim is to explain inner speech and thought, as well as the human capacity for self-conscious awareness. For him, the critical abilities are language and tool use. Both authors mention the “hard problem” of explaining how subjective experie...
Magnetic sensors work on the principle that metal passing in front of a magnetic field causes changes in the magnet field. The engine uses a gear-like wheel passing in front of the magnet to cause variations in the field, which tells the engine how fast the engine rotates. 3.What are the...
