Fleming's left hand rule for motors is a visual depiction used to determine direction of rotation in a motor.
Extend your thumb, index finger and middle finger of your left hand at right angles to each other.
The thumb represents direction of relative motion.
The index finger represents direction of flux (magnetic field).
The middle finger represents direction of current flow.
A simple way of remembering what each digit represent is the phrase: "Martha's Fresh Cookies." M being motion, F being flux and C being current.
Fleming's Right hand rule for generators is the same except you use your right hand and it applies to direction of rotation of generators.

What is the Difference between left hand rule and right hand rule?
Fleming's right hand rule shows the direction of induced current flow when a conductor moves in a magnetic field. Fleming's left hand rule shows the direction of the thrust on a conductor carrying a current in a magnetic field.
What is the motor effect?
When the current passes at right angles through a magnetic field, it experiences a force. The direction of the force is determined by Flemmings "Left Hand Motor Rule" This mechanical motion results from the interaction of the magnetic field which is known as the Motor Effect.
How do you know that a force is negative or positive in relation to magnetic field?
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.
When cathode rays are passed through a magnetic field which pole do they deflect towards north or south and why?
Cathode rays are electron beams. When they are moving in a magnetic field, they are deviated. The direction of their deflection is given by Fleming's left hand rule. The direction of deflection, current (which is the reverse of the direction of the electron beams) and field are all perpendicular to each other. Hence, the electron beam will deviate in a direction contained in a plane which is perpendicular to both the field and the electron beam. Hence, the cathode rays are neither defleted to the north nor south pole.
Which of these does not follow the octet rule NF3 CO2 OF2 Br2 NO?
See the Related Questions to the left for how to solve this problem.First draw the Lewis Dot structures of each molecule, then count the valence electrons of each atom in the structures. Find the one that doesn't have eight!In this case, there is actually a little trick. To follow the octet rule, each atom must have 8 valence electrons in the structure, right? Therefore, the molecule must have an even number of total electrons for that to work. So which molecule does not have an even number of total electrons?
How is the direction of magnetic field due to a straight conductor represented?
For conventional current, it is called the 'right hand rule'. Place your hand around the conductor (insulated of course) with your thumb pointing in the direction of (conventional) current flow. Your fingers represent the magnetic lines of force.

What hand do you put any ring for men?
Usually the left hand, though there is not a rule as to which hand or finger.
Is there a rule about always eating with a spoon in your left hand?
If there is, it is not an etiquette rule, and is not a rule of manners. It would be a custom, or a cultural rule. Maybe even a family rule. Etiquette says that a person eats with whichever hand they please.
What is the Difference between left hand rule and right hand rule?
Fleming's right hand rule shows the direction of induced current flow when a conductor moves in a magnetic field. Fleming's left hand rule shows the direction of the thrust on a conductor carrying a current in a magnetic field.
When was the left hand rule invented?
The left-hand rule, a rule used in physics to determine the direction of magnetic force in a conductor, was developed in the 19th century by scientists such as John Fleming and Oliver Heaviside. However, the specific date of its invention is not precisely recorded.
What is the left hand rule for conductors?
The left-hand rule for conductors states that if you point your thumb in the direction of the current flow and your fingers in the direction of the magnetic field, your palm will face in the direction of the force on the conductor. This rule helps to determine the direction of the force experienced by a current-carrying conductor in a magnetic field.
What is flaming left hand rule?
Stretch the thumb the first finger and the central finger of the left hand so that they are mutually perpendicular to each other. If the first four finger points in the direction of magnetic field the central finger points in the direction of current then the thumb points in the direction of motion of the conductor is known as fleming's left hand rule. by Prosenjit.
To use your left hand to determine the direction of the voltage developed in?
To use your left hand to determine the direction of the voltage developed in moving conductor place your forefinger in the direction of the lines of force. Fleming developed this hand rule.
When using the left hand rule for generator the thumb point in what dierction?
There is no left handed rule. The correct term is right handed rule. Using the right handed rule, your thumb is pointing in the direction of current flow, and your fingers are pointing in the direction of magnetic flux flow.
