Answer 1

Answer:

Hello mate

Explanation:

Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule[1] (for generators). They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.

Fleming's left-hand rule

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

Answer 2

Answer:

left hand Fleming's rules

if our first finger ,mid finger and thumb of left hand are perpendicular to each other ,and mid finger is in direction of current and Frist finger is in direction of magnetic field then our thumb will show the direction of force applied by magnetic field .
