state Fleming hand rule
Answers
Answer:
FLEMING'S LEFT HAND RULE
Stretch the thumb,fore finger and middle finger of your left hand such that they are mutually perpendicular to each other.If fore finger points in the direction of magnetic field,middle finger in the direction of current then thumb will point in the direction of motion or force
FLEMING'S RIGHT HAND THUMB RULE
Hold your thumb,fore finger and middle finger of right hand such that they are mutually perpendicular to each other. If your fore finger is in the direction of magnetic field and the thumb points in the direction of motion of conductor, then the direction of induced current Will be indicated by middle finger
Answer:
Fleming left hand rule state that when we keep our fore finger,centre finger and the thumb finger in right angles in such a way that fore finger give the direction of Magnetic field ,centre finger give the direction of Electric current then the thumb will point to the direction of mechanical force acting on it.
Fleming right hand rule for induced current state that when we keep our fore finger,centre finger and the thumb finger in right angles in such a way that fore finger give the direction of Magnetic field ,thumb point in the direction of motion of conductor then the centre finger gives the direction of induced current.
Point to notice=>
- This rule was applicqble in motor.
- There is another rule ex.Fleming right hand rule
- The mechanical force acting on it is perpendicular to the magnetic field.
