Maxwell’s right-hand thumb rule indicates the direction of magnetic field if the direction of current is known.
Thumb rules state that if thumb of the right hand points along direction of current, then the remaining curled , fingers of same hand gives the direction of the magnetic field due to the current.

1. The two temples the author visited in Kathmandu were the Pashupatinath temple and the Baudhnath stupa.
2. 'All this' refers to the author buying a bar of marzipan, a corn-on-the-cob roasted in a charcoal stove on the pavement (rubbed with salt, chilli powder and lemon), a couple of love story comics, and a Reader's Digest.
3. Vikram Seth compares the fifty or sixty bansuris protruding in all directions from the pole with an attachment on top that is held by the flute seller to the quills of a porcupine.
4. The five kinds of flutes are the reed neh, the Japanese shakuhachi, the deep bansuri of Hindustani classical music, the clear or breathy flutes of South America, and the high-pitched Chinese flute

In the Chinese view, art is a representation of the mind or the spirit, whereas in the European view, it is of the figure or the body. While Chinese paintings reveal the inner world, the European paintings lay emphasis on a true representation of the physical appearance of the subject.
The examples of paintings by Wu Daozi and Quinten Metsys are representative of this difference. The painting by Metsys is life-like. It is an exact representation of a fly. The painting of Daozi, on the other hand, is not only beautiful but alive too. It has a way within that only the painter is aware of.

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.

The modern Periodic law can be stated as: “The physical and chemical properties of the elements are periodic functions of their atomic numbers”. The atomic number is equal to the number of electrons or protons in a neutral atom.

Rust is a form of iron oxide. It occurs when iron combines with the oxygen in the air causing it to corrode. Rust can affect iron and its alloys, including steel. The main catalyst for rust to occur is water. Although iron and steel structures seem solid to the eye, water molecules are able to penetrate microscopic gaps in the metal. This starts the process of corrosion. If salt is present, for example in seawater, the corrosion will be more rapid. Exposure to sulfur dioxide and carbon dioxide will also hasten the corrosive process.
Rust causes the metal to expand, which can place great stress on the structure as a whole. At the same time, the metal will be weakened and become brittle and flaky. Rust is permeable to air and water, so the metal beneath the rust layer will continue to corrode.
How to Prevent Rust?
Exposure to outdoor conditions will increase the risk of rust, especially if the climate is rainy or humid. The best ways to prevent rust include:
Using rust resistant alloys
Design considerations
Galvanization
Bluing
Organic coating
Powder coating
Regular maintenance
Using Rust Resistant Alloys
The most popular rust resistant alloys are stainless steel and weathering steel.
Stainless steel contains a minimum of 11% chromium. This allows the formation of a protective film of chromium oxide which acts as a shield against rust. The protective film will re-form if damaged. Corrosion resistance can be further enhanced with the addition of nickel.
Weathering steel, also known as “COR-TEN” steel, contains up to 21% of alloying elements such as chromium, copper, nickel and phosphorous. The alloys form a protective rust patina which reduces the corrosion rate with time. COR TEN steel tends to be cheaper than stainless steel.
