Right hand grasp rule

The right hand rule is a hand mnemonic used in physics to identify the direction of axes or parameters that point in three dimensions.

In simple words, a current carrying conductor creates a magnetic field around it. The lines of magnetic flux are in the shape of concentric circles and perpendicular on the conductor at right angle of 90 o as shown in fig. The direction of current and magnetic field can be found by the following rules i. Related Posts:. The right hand rule is used to determine the direction of the magnetic field lines and current around a straight current carrying conductor, solenoid or coil inductor. The right hand thumb or grip rule shows if we hold the current carrying conductor in our right hand so that the thumb stretches to the conductor while the fingers wrapped around it, then the thumb shows the direction of current while the curly fingers shows the direction of magnetic field lines of force.

In mathematics and physics , the right-hand rule is a convention and a mnemonic , utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors , as well as to establish the direction of the force on a current-carrying conductor in a magnetic field. The various right- and left-hand rules arise from the fact the three axes of three-dimensional space have two possible orientations. This can be seen by holding your hands together with palms up and fingers curled. If the curl of the fingers represents a movement from the first or x-axis to the second or y-axis, then the third or z-axis can point along either right thumb or left thumb. The right-hand rule dates back to the 19th century when it was implemented as a way for identifying the positive direction of coordinate axes in three dimensions. William Rowan Hamilton , recognized for his development of quaternions , a mathematical system for representing three-dimensional rotations, is often attributed with the introduction of this convention. In the context of quaternions, the Hamiltonian product of two vector quaternions yields a quaternion comprising both scalar and vector components. Following a substantial debate, [2] the mainstream shifted from Hamilton's quaternionic system to Gibbs' three-vectors system. This transition led to the prevalent adoption of the right-hand rule in the contemporary contexts. The right-hand rule in physics was introduced in the late 19th century by John Fleming in his book Magnets and Electric Currents.

A list of physical quantities whose directions are related by the right-hand rule is given below. This causes the Sun, Moon, and stars to appear to revolve westward according to the left-hand rule.

The right hand rule is a hand mnemonic used in physics to identify the direction of axes or parameters that point in three dimensions. Invented in the 19th century by British physicist John Ambrose Fleming for applications in electromagnetism, the right hand rule is most often used to determine the direction of a third parameter when the other two are known magnetic field, current, magnetic force. There are a few variations of the right hand rule, which are explained in this section. When a conductor, such as a copper wire, moves through a magnetic field B , an electric current I is induced in the conductor. This phenomenon is known as Faraday's Law of Induction.

Torques that occur in a counter clockwise direction are positive torques. IEEE Access. No part of the body is moving in the direction of the axis arrow. There are a few variations of the right hand rule, which are explained in this section. These operations can be composed to give repeated changes of handedness. We can use Fleming's right hand rule to investigate Faraday's Law of Induction, which is represented by the equation:. If we consider the flow of charges in two different wires, one with positive charges flowing up the page, and one with negative charges flowing up the page, then the direction of the magnetic forces will not be the same, because we are considering two different physical situations. Then, point your index finger in the direction of vector a and your middle finger in the direction of vector b. John Ambrose Electrical Technology 1 3 minutes read. Table of Contents Toggle.

The magnetism right-hand rule, also known as the right-hand grip rule, is a powerful tool used to determine the direction of magnetic fields around a current-carrying conductor. By applying this rule, one can quickly grasp the complex interactions between magnetic fields and electric currents. One of the fascinating phenomena explained by the magnetism right hand rule is electromagnetic induction.

A helix is a curved line formed by a point rotating around a center while the center moves up or down the z -axis. In the context of quaternions, the Hamiltonian product of two vector quaternions yields a quaternion comprising both scalar and vector components. John Hamal In the first wire, the flow of positive charges up the page indicates that negative charges are flowing down the page. Rather, the definition depends on chiral phenomena in the physical world, for example the culturally transmitted meaning of right and left hands, a majority human population with dominant right hand, or certain phenomena involving the weak force.

If you hold the coil or a solenoid in the right hand so that the four fingers curl around the coil or solenoid, then the curly figures show the direction of the current and the thumb represents the North Pole of the coil.
