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. Invented in the 19th century right hand grasp rule 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.

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 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. Your hand should look similar to this: In the diagram above, the thumb aligns with the z right hand grasp rule, the index finger aligns with the x axis and the middle finger aligns with the y axis.

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 direction of your fingers will mirror the curled direction of the induced magnetic field. When this occurs, the charged particle can maintain its straight line motion, even in the presence of a strong magnetic field. These operations can be composed to give repeated changes of handedness. 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. For the traffic rule, see Priority to the right. 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. We can use the right hand rule to identify the direction of the force acting on the current-carrying wire.

The direction of the cross product may be found by application of the right-hand rule as follows:. Electrical Technology 1 3 minutes read. This means that the primary and secondary magnetic fields will occur in opposite directions. In vector calculus , it is necessary to relate a normal vector of a surface to the boundary curve of the surface. Negative charges will be affected by a force in the opposite direction. Read Edit View history. For the maze-solving technique, see Wall follower. Then, point your index finger in the direction of vector a and your middle finger in the direction of vector b. 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. Next, align your thumb in the direction of the induced magnetic field and curl your fingers. 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. When an electric current passes through a solenoid, it creates a magnetic field. When the length of the wire and the magnetic field are at right angles to one another, then the equation becomes:. Teaching Tools Wireless Smart Cart 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.
