exceptions of rule of thumb

Imagine the conductor to be held in your right hand with the fingers curled around it. If the thumb points in the direction of the current, then the curled fingers show the direction of the magnetic fie..

While the octet rule is very useful for describing bonding in a large number of compounds, there are many exceptions to this rule..

Physical, chemical and mathematical sciences follow a specific set of rules and regulations. They are governed by a set of laws such as the law of gravity, the laws of thermodynamics, the law of conservation of mass and so on. However, biological sciences, in the strict sense, do no..

The direction of the current in a wire moving perpendicular to itself and to a magnetic field may be found by Fleming's right hand rule. If the thumb, forefinger and middle finger of the right hand are stretched in a mutually perpendicular direction, in such a way that the fore..

The direction of induced current can easily be predicted using Fleming's right hand rule. If we stretch the first finger, the central finger and the thumb of our right hand in mutually perpendicular directions such that first finger points along the direction of the field and th..

If a wire carrying a current is gripped with the right hand and with the thumb pointing along the wire in the direction of the current, then the fingers point in the direction of the magnetic field around the wi..

Extend the thumb, forefinger, and the middle finger of the left hand in such a way that all the three are mutually perpendicular to each another. If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thumb..

Imagine a right-handed corkscrew being rotated along the wire in the direction of the current. The direction of rotation of the thumb gives the direction of the magnetic lines of force...

The direction of the magnetic field around a current carrying conductor can be explained by a simple rule known as Maxwell's right hand grip rule. If we hold the current carrying wire in our right hand in such a way that the thumb is stretched along the direction of th..
