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.The forefinger indicates the direction of the magnetic field; the middle finger indicates the direction of the current and the thumb represents the direction of the motion.When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow. A left hand can be held, as shown in the illustration, so as to represent three mutually orthogonal axes on the thumb, forefinger and middle finger.The left-hand rule requires you to“Hold out your left hand with the forefinger, second finger and thumb perpendicular to each other. If the forefinger represents the direction of the field and the second finger represents that of the current, then thumb gives the direction of the force.”
ㅤ➪There is no electric feild near a long straight thin ㅤㅤㅤㅤㅤuniform current carrying conductor.
ㅤ➪Therefore, a charged particle moving parallel to ㅤㅤㅤㅤㅤthe conductor experiences a magnetic force as per ㅤㅤㅤthe electrodynamics.
ㅤ➪The Left Hand Flemings Rule came in existence ㅤㅤㅤㅤㅤthrough John Ambrose Fleming in the 19th century.
ㅤ➪It was the simplest approach to understand the ㅤㅤㅤㅤㅤdirection of the electric current.
ㅤ➪The left hand rule of Fleming states that when we ㅤㅤㅤㅤstretch the forefinger and middle finger of left hand ㅤㅤㅤin a manner that they are mutually perpendicular to ㅤㅤㅤeach other.
ㅤ➪Now, If the forefinger is taken as the direction of the ㅤㅤㅤcurrent and the middle finger towards the magnetic ㅤㅤㅤfield then the thumb point towards the motion of the ㅤㅤㅤconductor of the force.
ㅤ➪It Is One of the rule of electricity.
ㅤ➪The Reason behind the current-carrying the conductor ㅤㅤcomes under the magnetic feid there is likely to be a ㅤㅤforce acting on the conductor.
ㅤ➪With the help of flemings left hand rule, the director ㅤㅤㅤof the force can be determined.
