There is also a Fleming's left-hand rule (for electric motors). The appropriately handed rule can be recalled from the letter "g", which is in "right" and "generator". These mnemonics are named after British engineer John Ambrose Fleming, who invented them. An equivalent version of Fleming's right-hand rule is the left-hand palm rule. [2]
Right-hand rule for cross product. The cross product of vectors and is a vector perpendicular to the plane spanned by and with the direction given by the right-hand rule: If you put the index of your right hand on and the middle finger on , then the thumb points in the direction of . [4] Fleming's right hand rule
Fleming's rules are a pair of visual mnemonics for determining the relative directions of magnetic field, electric current, and velocity of a conductor. [1]There are two rules, one is Fleming's left-hand rule for motors which applies to situations where an electric current induces motion in the conductor in the presence of magnetic fields (Lorentz force).
The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.
The magnetic field is more concentrated and thus stronger on the left edge of the copper bar (a,b) while the field is weaker on the right edge (c,d). Since the two edges of the bar move with the same velocity, this difference in field strength across the bar creates whorls or current eddies within the copper bar.
The placement of objects like pens and gearshifts is also typically geared toward those with a dominant right hand. Here are 19 simple, daily tasks or experiences that can be a hassle for left ...
Sir John Ambrose Fleming (29 November 1849 – 18 April 1945) was an English electrical engineer and physicist who invented the vacuum tube, [2] designed the radio transmitter with which the first transatlantic radio transmission was made, and also established the right-hand rule used in physics.
There's been an ongoing debate about whether retirees should abandon the "4% rule" for withdrawals from retirement accounts, a retirement income rule of thumb for decades. The market volatility of ...
