Right hand grasp rule

The right hand rule is a hand mnemonic used in right hand grasp rule 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 brothel granville third parameter when the other two are known magnetic field, current, magnetic force.

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. For right-handed coordinates, if the thumb of a person's right hand points along the z -axis in the positive direction third coordinate vector , then the fingers curl from the positive x -axis first coordinate vector toward the positive y -axis second coordinate vector. Interchanging the labels of any two axes reverses the handedness. Reversing the direction of one axis or three axes also reverses the handedness. These operations can be composed to give repeated changes of handedness.

Lenz's law states that the direction of the current induced in a closed conducting loop by a changing magnetic field Faraday's Law is such that the secondary magnetic field created by the induced current opposes the initial change in the magnetic field that produced it, 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. This process occurs when a conductor moves through a magnetic field or when there is a change in the magnetic flux through a circuit. Electromagnetic induction is the foundation of various electrical devices, including generators and transformers. When a conductor moves through a magnetic field, the magnetism right hand rule enables us to predict the induced direction of the current flow in the conductor. The interaction between the magnetic field and the moving conductor generates an electromotive force EMF that induces the current.

One Comment. Step by Step Procedure with Solved Example. 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. Helices are either right or left handed with curled fingers giving the direction of rotation and thumb giving the direction of advance along the z -axis. A list of physical quantities whose directions are related by the right-hand rule is given below. 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. 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. 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. Back to Top. Since a conventional current is composed of positive charges, then the same current-carrying wire can also be described as having a current with negative charge carriers moving down the page.

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. Your right thumb will point in the direction of the vector product, a x b vector c. This means that the primary and secondary magnetic fields will occur in opposite directions. 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. For example, as discussed above, the force exerted on a moving charged particle when moving in a magnetic field B is given by the magnetic term of Lorentz force:. The strength of the magnetic field passing through a wire coil determines the magnetic flux. Related Posts:. For example, for a positively charged particle moving to the north, in a region where the magnetic field points west, the resultant force points up. Following a substantial debate, [2] the mainstream shifted from Hamilton's quaternionic system to Gibbs' three-vectors system. Lenz's law of electromagnetic induction is another topic that often seems counterintuitive, because it requires understanding how magnetism and electric fields interact in various situations.
