Unlocking the Potential of Electromagnetism: Theory
A force perpendicular to the field and the direction of the current flow is applied to a current-carrying conductor when it is exposed to an external magnetic field. The direction of the force exerted on a current-carrying conductor in a magnetic field is determined using the Fleming left-hand rule.
The thumb points to the direction of the applied force experienced by either conductor, the forefinger points to the direction of the magnetic field, and the middle finger points to the position of the electric current, according to Fleming's Left Hand Rule, if we arrange our left thumb, forefinger, and middle finger perpendicular to each other.
Fleming’s Left Hand Rule
What is Fleming Right Rule:
According to Faraday's law of electromagnetic induction, an electric current is induced in a magnetic flux when a current passes through it. The direction of the induced current is determined using Fleming's right-hand rule.
The thumb points to the direction of the conductor's motion with respect to the magnetism, the forefinger points to the magnetic field, and the middle finger points to the induced current, according to Fleming's Right Hand Rule, if we arrange the thumb, forefinger, and middle finger on our right hand perpendicular to one another.
Fleming’s Right Hand Rule
Application of Fleming Left Hand Rule and Right Hand Rule:
The left-hand rule and the right-hand rule are two visual representations in the field of electromagnetism developed by Fleming. In practise, these criteria are only used to determine the direction of the consequent - either current or force - as a convenient way to understand the idea of relationship of current, magnetic field and the resultant force. The Lorentz' Force is what determines the magnitude of that force along the path.
Differentiate Between Fleming Left and Right Rule:
Summary
It is crucial to differentiate between fleming left and right rule because these are two key ideas in the chapter on electromagnetism. Fleming's left-hand rule is applied to electric motors, whereas Fleming's right-hand equation is applied to electric generators. To put it another way, you should utilise Fleming's left hand rule to create motion, while you should use Fleming's right hand rule to create electricity. According to Faraday's law of electromagnetic induction, an electric current is induced in a magnetic flux when a current passes through it. A force perpendicular to the field and the direction of the current flow is applied to a current-carrying conductor when it is exposed to an external magnetic field.
FAQs on Difference Between Fleming Left and Right Rule
1. What is fleming left and right rule?
A force perpendicular to the field and the direction of the current flow is applied to a current-carrying conductor when it is exposed to an external magnetic field. A current-carrying conductor's force in a magnetic field can be determined using the Fleming left-hand rule. However, to ascertain the direction of the induced current, Fleming's right-hand rule is applied. The thumb points to the direction of the conductor's motion with respect to the magnetism, the forefinger points to the magnetic field, and the middle finger points to the induced current if we align the thumb, forefinger, and middle finger of our right hand perpendicular to one another, according to Fleming's Right Hand Rule.
2. In a horizontal plane, the magnetic force acting on a travelling electron is directed southward. What direction of the magnetic field will there be if the electron is travelling vertically upward?
Current flows in the direction opposite of the electron's motion. Thus, according to the question, with respect to the horizontal plane, the current is moving downward. On the horizontal plane, magnetic force is exerted towards the south. As a result, we can infer from Fleming's left-hand rule that the magnetic field is pointing eastward on a horizontal plane.
3. Which rule is used for electric motors and electric generators?
For electric motors, Fleming’s left hand rule is applied to get the direction of force exerted by magnetic field and current. For example, in a fan, the electric motor works on the principle of Fleming’s left hand rule. For electric generators, Fleming’s right hand rule is applied to get the direction of induced electric current due to the influence of magnetic field and thrust applied. For example, the working of dynamo is based on the principle of Fleming’s right hand rule.
