Question

what is Flemming's left hand rule? explane

Answer 1

When current flows through a conducting wire, and an external magnetic field is applied across that flow, the conducting wire experiences a force perpendicular both to that field and to the direction of the current flow (i.e they are mutually perpendicular) . A left hand can be held, as shown in the illustration, so as to represent three mutually orthogonal axes on the thumb, fore finger and middle finger. Each finger is then assigned to a quantity (mechanical force, magnetic field and electric current). The right and left hand are used for generators and motors respectively.

Answer 2

$\huge\textbf{Fleming's Left Hand}$

$\huge\textbf{Rule :}$



Stretch your thumb, middle finger (first finger) and second finger.

All are mutually perpendicular to each other.

In this thumb represent motion.

First finger represent magnetic field.

And Second finger represent current.

Whenever a current carrying conductor is placed in a magnetic field, it experiences a force due to the magnetic field. This is known as Fleming's Left Hand Rule.
