The earth’s magnetic field:
The earth acts as a magnet and the lines of force produced by it follow the pattern shown in the diagram below.
If the Earth were completely symmetrical, the north and south magnetic poles would coincide with the axis of the Earth. The magnetic poles are, in fact, separated from the true poles by about 1000 Miles, the north magnetic pole being in the area 70 - 75 degrees North and roughly 95 degrees West.
Since the North pole of a magnet is really a North seeking pole and similarly the South pole is really a South seeking pole it follows that at the Earth's North pole there must be a south seeking magnet and similarly at the Earth's South pole there must be a North seeking magnet. Unfortunately before the significance of the Earth's magnetism was realised, navigators had dropped the word "seeking" leaving the embarrassing statement that there is a magnetic south pole at the North pole and a magnetic North pole at the South pole.

Gauss' law for magnetic fields (K.F. Gauss) The magnetic flux by a closed surface is zero; no magnetic charges present; in differential form, div B = 0.
Calculation of number of atoms per unit cell The number of atoms per unit cell occurs on the crystal structure and the kind of basic elements (basis or pattern unit or motif) t
Pascal's principle: Pressure applied onto an enclosed incompressible static fluid is transmitted undiminished to all of the parts of the fluid.
Simple Harmonic Motion II In physics, simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement. It can serve a

Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
What is Fission and Fusion? Fission: The breaking down of a Nucleus (not atom) into minute nuclei. It is usually induced by a neutron. For instance, a Helium nucleus (known a
