Is Fleming left hand rule for positive charge?

Fleming’s rule therefore uses the left hand to describe positive charges (as a conventional current is the flow of positively charged moving particles) and uses the right hand to describe negative charges. A conventional current running through a conducting wire creates a magnetic field around the wire.

In which case is the Fleming left hand rule applicable?

In an electric 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.

What is the direction of Fleming left hand rule?

Application of Fleming’s left-hand rule The direction of force is towards the north as the magnetic field is acting downwards. Therefore, we can say that the direction of the force acting is towards the north. 2.

Can Fleming’s right hand rule can be used to find the direction of magnetic field?

Fleming’s right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings.

What is the left hand rule in math?

The left hand rule is an approximate method for finding the area under the curve f(x) between the limits x=a and x=b which uses the formula: abf(x)dx=h(f(x0)+f(x1)+ +f(xn−1))

What is the indication of middle finger in Flemings 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 …

Which of the following statement regarding Fleming’s rule is correct?

The correct answer is Fleming’s left-hand rule gives the direction of the force on a current-carrying conductor in a magnetic field. When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow.

Why does left hand rule work?

When a wire carrying an electric current is moved in a magnetic field of a magnet the magnetic field induced by the wire reacts with the magnetic field of the magnet causing the wire to move outwards. Fleming’s left hand rule helps you to predict the movement.

What is the difference between left handed and right handed Cartesian coordinate system?

For left-handed coordinates use left hand. For right-handed coordinates the right thumb points along the z axis in the positive direction and the curl of the fingers represents a motion from the first or x axis to the second or y axis. When viewed from the top or z axis the system is counter-clockwise.

What is difference between left hand and right hand rule?

Key Difference: The Left Hand Rule and Right Hand Rule are types of visual mnemonics that were developed by John Ambrose Fleming in the late 19th century. They are used to show the direction of the motion, field and current. The Left Hand Rule applies to electric motors, while the Right Hand Rule applies to generators.

What is Flemings left hand rule in Electrical Engineering?

Answer Wiki. Basically, Flemings left hand rule is used to find the direction of force on the conductor.Here we take current direction from positive side to negative side(conventional current) and then we apply flemings left hand rule .

What does the thumb indicate in Fleming’s right hand rule?

Interpreting Fleming’s Right-Hand Rule The thumb indicates the direction of the motion; the forefinger indicates the direction of the magnetic field and the middle finger represents the direction of the induced current.

What is Fleming’s Law of electromagnetic induction?

Fleming Right Hand Rule As per Faraday’s law of electromagnetic induction, whenever a conductor moves inside a magnetic field, there will be an induced current in it. If this conductor gets forcefully moved inside the magnetic field, there will be a relation between the direction of applied force, magnetic field and the current.

How do you find the direction of force on a conductor?

The direction of this force can be found using Fleming’s Left Hand Rule (also known as ‘Flemings left-hand rule for motors’). Similarly if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor. The direction of this force can be found using Fleming’s Right Hand Rule.
