Question

explain the rule of Fleming left hand

Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.
Whenever a current carrying conductor is placed in a magnetic field, the conductor experiences a force which is perpendicular to both the magnetic field and the direction of current. According to Fleming's left hand rule, if the thumb, fore-finger and middle finger of the left hand are stretched to be perpendicular to each other as shown in the illustration at left, and if the fore finger represents the direction of magnetic field, the middle finger represents the direction of current, then the thumb represents the direction of force. Fleming's left hand rule is applicable for motors.

How To Remember Fleming's Left Hand Rule?

Relate the Fleming's left-hand rule with FBI (wait! NOT with the Federal Bureau of Investigation). Here, F for Force, B is the symbol of magnetic flux density and I is the symbol of Current. Attribute these letters F,B,I to the thumb, first finger and middle finger respectively.

I HOPE IT HELPS U.

$\large\underline{Fleming \:Left \:Hand\: Rule:-}$

✔️According to this rule, stretch the thumb, forefinger and middle finger of your left hand such that they are mutually perpendicular.

✔️If the forefinger points in the direction of magnetic field and the middle finger in the direction of current, then the thumb will point in the direction of motion or the force acting on the conductor.

Hope it helps you!!
