Hypsometer and the Effect of Altitude On Boiling Point
The pressure of the atmosphere decreases with increasing height above the earth’s surface, because the thickness, and therefore the weight, of the belt of air…

Tabular Description of the Properties of Magnetic Materials
Magnetic Material: Steel is more suitable for permanent magnets, because it high coercivity meaning that it is not easily demagnetized by shaking. The fact that…
Application of Doppler Effect in the Measurement of Light
In understanding the application of Doppler effect on the measurement of light, we must note that the speed of distant stars and planet has been…
Detailed Description of Resonance in Sound and Mechanics
If a diving springboard is bent and then allowed to vibrate freely, it oscillates with a frequency which is called its natural frequency. When a…
Electrostatic Shielding in an Electric Field
Electrostatic shielding: The fact that there is no electric field inside a close conductor, when it contains no charged bodies, was demonstrated by Faraday in…
Explanation of Ferromagnetism and Magnetic Domain
A ferromagnetic material has a very high value of susceptibility, χ, and hence of relative permeability, µr. The value of µr can be several thousands….
