How do you know when to use right hand or left hand rule?

Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. In other words, Fleming’s left hand rule should be used if one were to create motion, while Fleming’s right hand rule should be used if one were to create electricity.

What is the difference between Fleming’s left and Right Hand Rule?

Fleming’s left-hand rule gives the direction of magnetic force acting on a conductor whereas Fleming’s right-hand rule is used to find the direction of induced current.

In what situation do we use Fleming’s Right Hand Rule?

In what situation do we use Fleming’s right hand rule? Fleming’s right hand rule helps us to determine the direction of induced current in a conductor moving perpendicular to a magnetic field.

When we use Fleming left hand rule?

Fleming’s Left-Hand Rule is a simple and accurate way to find the direction of force/motion of the conductor in an electric motor when the magnetic field direction and the current direction are known. It was originally developed by John Ambrose Fleming, an English electrical engineer, in the late 19th century.

What is Flemings right hand rule Class 10?

Fleming’s right hand rule states to hold the forefinger, middle finger and thumb of right hand mutually perpendicular to each other so that the forefinger points in the direction of external magnetic field and thumb points in the direction of motion of conductor.

What is the use of the right hand rule?

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in the direction of the the resulting magnetic force …

In which appliance is Fleming left hand rule not used?

Fleming left hand rule is used to identify the direction of force or thrust when current is passing through any wire or coil. in above options , computer is not where force/motion lead to perform. hence, option (c) is correct.

What does thumb indicates according to Fleming left hand rule?

According to Fleming’s left hand rule, if the thumb, fore-finger and middle finger of the left hand are stretched to be perpendicular to each other as shown in the illustration at left, and if the fore finger represents the direction of magnetic field, the middle finger represents the direction of current, then the …

Why do we use right hand screw rule?

The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. Therefore if the direction of rotation is know the fingers can be curled in this orientation and the thumb will point in the positive direction, and vice versa.

What is left hand screw rule?

If you point your thumb in the direction of the current, as shown, and let your fingers assume a curved position, the magnetic field circling around those wires flows in the direction in which your four fingers point. The Left Hand Rule shows what happens when an electrical current enters a magnetic field.
