Fleming's right hand rule (for generators) shows the direction of induced current flow when a conductor moves in a magnetic field.
The right hand is held with the thumb, first finger and second finger mutually at right angles, as shown in the diagram below.
The Thumb represents the direction of Motion of the conductor.
The First finger represents Field.
The Second finger represents Current (in the classical direction, from positive to negative).
There also exists Fleming's left hand rule (for motors). You can remember which rule to use by recalling that the letter "g" is in "right" and "generator". Flemings left hand rule (for motors) shows the direction of the thrust on a conductor carrying a current in a magnetic field. ...
This mnemonic is named after British engineer John Ambrose Fleming, who invented it. A mnemonic (pronounced in American English, in British English) is a memory aid. ... Sir John Ambrose Fleming (), (November 29, 1849 - April 18, 1945) was an English electrical engineer and physicist. ...
Again, the rule is none the less the rule, nor the exceptions the exceptions, because the exceptions may easily outnumber the instances which conform to the rule.
The rule is still the rule, because take the instances which conform to it as a matter of course, while in every case which does not conform to it we ask for the explanation.
But, on the other hand, where French or Danish or Slavonic or Lithuanian is spoken within the bounds of the new empire, the principle that language is the badge of nationality, that without community of language nationality is imperfect, shows itself in another shape.
