Right hand grasp rule

In simple words, a current carrying conductor creates a magnetic field around it, right hand grasp rule. 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:.

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.

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. If the conductor is moved inside the magnetic field, then there is a relationship between the directions of the conductor's motion velocity , magnetic field and the induced current. We can use Fleming's right hand rule to investigate Faraday's Law of Induction, which is represented by the equation:. Because the x, y and z axes are perpendicular to one another and form right angles, the right hand rule can be used to visualize their alignment in three-dimensional space. To use the right hand rule, begin by making an L-shape using your right thumb, pointer and middle finger. Then, move your middle finger inwards toward your palm, so that it is perpendicular to your pointer finger and thumb. 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. One of the best ways to help students become confident using the right hand rule, is to perform a visual demonstration that helps them recognize and correct their misconceptions about orthogonal relationships and coordinate systems. A charged particle is a particle with an electric charge. When a motionless charged particle exists in a magnetic field, it does not experience a magnetic force; however, as soon as the charged particle moves within a magnetic field, it experiences an induced magnetic force that displaces the particle from its original path.

To use the right hand grip rule, point your right thumb in the direction of the current's flow and curl your fingers. Alternatively, torques that occur in the clockwise direction are negative torques.

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.

Right hand grasp rule

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.

The cross product of vectors a and b, is perpendicular to both a and b and is normal to the plane that contains it. Privacy Policy Index. The induced current creates a secondary magnetic field that opposes the original change in flux that initiated the induced current. Products Index. An elementary treatise for the use of electrical artisans and science teachers. Any Keyword Exact Match. Next, align your thumb in the direction of the induced magnetic field and curl your fingers. To use the right hand rule in torque problems, take your right hand and point it in the direction of the position vector r or d , then turn your fingers in the direction of the force and your thumb will point toward the direction of the torque. The direction of your fingers will mirror the curled direction of the induced magnetic field. 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. The strength of the magnetic field passing through a wire coil determines the magnetic flux.

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

University of Delaware. Right hand rule can also be used for determination of the magnetic field orientation and direction. Leave a Reply Cancel reply Your email address will not be published. Electrical Technology 1 3 minutes read. Interchanging the labels of any two axes reverses the handedness. Torques that face out from the paper should be analyzed as positive torques, while torques that face inwards should be analyzed as negative torques. In this model, your fingers point in the direction of the magnetic field, your thumb points in the direction of the conventional current running through the wire, and your palm indicates the direction that the wire is being pushed force. The cross product of vectors a and b, is perpendicular to both a and b and is normal to the plane that contains it.
