Difference between the right hand thumb rule and left hand thumb rule?

Question

Answer

I DON'T KNOW ANY LEFT HAND THUMB RULE BUT THERE IS A RIGHT HAND THUMB RULE WHICH IS:-

#Right hand thumb rule:- According to right hand thumb rule when we clutches a current carrying conductor by our right hand and aur thumb points in the direction of current then the direction in which our all other fingers bend, shows the direction of magnetic field formed by current carrying conductor.

Thank you.. :-)

Answer

Fleming's left-hand rule is used for electric motors, while Fleming's right-hand rule is used for electric generators. ... In anelectric motor, the electric current and magnetic field exist (which are the causes), and they lead to the force that creates the motion (which is the effect), and so the left hand rule is used.

Answer

Answer

Fleming's left-hand ruleis used for electric motors, while Fleming'sright-hand rule is usedfor electric generators. ... Since neither the direction of motion nor the direction of the magnetic field (inside the motor/generator) has changed, the direction of the electric current in the motor/generator has reversed.

Answer

1.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.

2.Fleming's left-hand rule is used to find the direction of magnetic force acting in an electric motors.

while

Fleming's right-hand rule is used to find the direction of induced current in an electric generators.

Answer

In right hand thumb rule current is induced.but in left hand rule no current is induced in the circuit.

Answer

Introduction:

The right hand thumb rule and left hand thumb rule are two commonly used rules in physics and engineering to determine the direction of certain physical quantities such as magnetic fields, forces, and moments. These rules are based on the principles of electromagnetism and are used to make predictions and solve problems in various fields.

Difference between the Right Hand Thumb Rule and Left Hand Thumb Rule:

Right Hand Thumb Rule:

The right hand thumb rule is used to determine the direction of the magnetic field around a current-carrying conductor or a straight wire. It follows the convention that the thumb points in the direction of the current flow and the curled fingers represent the direction of the magnetic field lines around the wire. Here's how the right hand thumb rule works:

1. Direction of Current: Point the right thumb in the direction of the current flow in the wire.
2. Direction of Magnetic Field: The curled fingers of the right hand will represent the direction of the magnetic field lines around the wire.

This rule is based on the concept of the magnetic field created by a current-carrying wire forming concentric circles around it.

Left Hand Thumb Rule:

The left hand thumb rule is used to determine the direction of forces and moments experienced by a current-carrying conductor placed in a magnetic field. It follows a different convention than the right hand thumb rule. Here's how the left hand thumb rule works:

1. Direction of Magnetic Field: Point the left thumb in the direction of the magnetic field lines.
2. Direction of Current: The curled fingers of the left hand represent the direction of the current flow in the conductor.

This rule is based on the principles of electromagnetic induction and the Lorentz force law, which states that a current-carrying conductor experiences a force perpendicular to both the direction of the current and the magnetic field.

Summary:

In summary, the right hand thumb rule is used to determine the direction of the magnetic field around a current-carrying conductor, while the left hand thumb rule is used to determine the direction of forces and moments experienced by a current-carrying conductor in a magnetic field. The right hand thumb rule focuses on the relationship between current and magnetic field, while the left hand thumb rule focuses on the relationship between magnetic field and force. Both rules are essential tools in understanding and solving problems related to electromagnetism.
