Write Fleming's left hand rule and explain the points.i principle working and fig. Of
mother.
Answer:​

Answer 1

Answer:

When a current-carrying conductor is placed under a magnetic field, a force acts on the conductor. The direction of this force can be identified using Fleming’s Left Hand Rule. Likewise, if a moving conductor is brought under a magnetic field, electric current will be induced in that conductor. The direction of the induced current can be found using Fleming’s Right Hand Rule. It is important to note that these rules do not determine the magnitude, instead show only the direction of the three parameters (magnetic field, current, force) when the direction of the other two parameters is known. Fleming’s Left-Hand Rule is mainly applicable to electric motors and Fleming’s Right-Hand Rule is mainly applicable to electric generators.
