Right hand thumb rule: The Right Hand Thumb Rule

Right Hand Thumb Rule The Right Hand Thumb Rule , also known as the Right Hand Grip Rule or the Right Hand Rule , is a simple rule used in physics and electromagnetism to determine the direction of the magnetic field produced by the current flowing through a wire. It was devised by British scientist John Ambrose Fleming in the late 19th century. What Is Fleming’s Right - Hand Rule ? According to Faraday’s law of electromagnetic induction, when a conductor moves through a magnetic field, an electric current is induced in it. Fleming’s right - hand rule is used to determine the direction of the induced current. Fleming’s Right Hand Rule states that if we arrange our thumb , forefinger and middle finger of the right - hand perpendicular to each other, then the thumb points towards the direction of the motion of the conductor relative ... Assuming current flows in ... 3.1.2 Right Hand Rule and Torque The third way to calculate torque, as was alluded to in Section 1.6 is to use the right hand rule to identify the axis of rotation. The first way (the scalar method) uses | M | = | r | | F | sin Θ, and often the angle between the position vector and force is 90 degrees. The vector method is for more complicated situations and uses the cross product r x F= M. The third method finds the scalar value separately, then uses the right hand rule to find the ...
