Diamagnetic Substance
Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic moment. [Their orbital and spin magnetic moment add vectorially to become zero]. The atoms..
Directive property
When a bar magnet is suspended freely, it always comes to rest in a north-south direction. This property is used in the construction of a mariner's compass. ..

A magnet attracts magnetic substances like iron, steel etc. This property is used to separate iron from a mixture, to remove iron filings from the eye et..
Properties of Matter
Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystallin..

Wave Properties
On observing waves, it may be observed that they travel with a definite speed through a uniform medium. If we watch a particular spot, we find that the waves pass that spot at regular intervals of time. The following definitions help in describing wave motio..
The Zero Vector and its Properties
The Zero Vector and its Properties - Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we cannot take the above result to be a numb..

Properties of Magnetic Lines of Force
Magnetic lines of force form closed continuous curves. Outside the body of the magnet, their direction is from north to south pole. The tangent to these lines at any point gives the direction of the magnetic field at that point. No two lines can intersect each other. The lines of forc..

Even though I don't feel good, the tutor helped me by totally helping me understand!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
