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, right hand grasp rule. Invented in the 19th century by British physicist John Right hand grasp rule 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 Ban electric current I is induced in the conductor.

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.

In both situations, the right hand grip rule is applied to two applications of Ampere's circuital law, right hand grasp rule, which relates the integrated magnetic field around a closed loop to the electric current passing through the plane of the closed loop.

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.

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. Your hand should look similar to this: In the diagram above, the thumb aligns with the z axis, the index finger aligns with the x axis and the middle finger aligns with the y axis. My Cart. Your hand should look similar to this:. To apply the right hand grip rule, align your thumb with the direction of the conventional current positive to negative and your fingers will indicate the direction of the magnetic lines of flux. Download as PDF Printable version. A charged particle is a particle with an electric charge. If the thumb is pointing north, Earth rotates according to the right-hand rule prograde motion. Let's break it down. My Account Sign In. Ithaca, NY : Matrix Editions. Wikimedia Commons.

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.

This phenomenon, also known as Lorentz force, is consistent with the rule that states, "magnetic fields do no work. To use the right hand grip rule in a solenoid problem, point your fingers in the direction of the conventional current and wrap your fingers as if they were around the solenoid. Torques that face out from the paper should be analyzed as positive torques, while torques that face inwards should be analyzed as negative torques. For the maze-solving technique, see Wall follower. To apply the right hand grip rule, align your thumb with the direction of the conventional current positive to negative and your fingers will indicate the direction of the magnetic lines of flux. The relation between current and magnetic field is shown in the following fig using cork screw rule. In the diagram above, the thumb aligns with the z axis, the index finger aligns with the x axis and the middle finger aligns with the y axis. The strength of the magnetic field passing through a wire coil determines the magnetic flux. An elementary treatise for the use of electrical artisans and science teachers. Electronics Engineering. Some of these are related only indirectly to cross products, and use the second form.
