The index finger points in the direction of the velocity vector v. The middle finger points in the direction of the magnetic field vector B. The thumb points in the direction of the cross product F. 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 ...
The right hand is held with the thumb, index finger and middle finger mutually perpendicular to each other (at right angles), as shown in the diagram. [1] The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field. The first finger is pointed in the direction of the magnetic field. By convention, it's ...
A space exists between the thumb and the tip into which a small object can be concealed. [1] For the vanish, the tip is already in the left fist. The handkerchief or cigarette is pressed into the tip with the fingers and then finally the right thumb, which comes quickly out of the hand with the tip on and the object inside, between the tip and ...
Fleming's left-hand rule. Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule for generators. [1] [2] [3] They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
This would lead to right axis deviation findings on an ECG. [6] Bifascicular block is a combination of right bundle branch block and either left anterior fascicular block or left posterior fascicular block. Conduction to the ventricle would therefore be via the remaining fascicle.
TikTok may be more famous for its viral dance trends, but an alleged constipation hack is getting plenty of attention, too.. Earlier this month, the TikTok account for Empirical Grace Acupuncture ...
The fingers are numbered sequentially from "1" for the index finger, to "4" for the little finger, to the letter "T" for the thumb. Finger slots are represented by placing any two or more of these together. For example, the space between the index and middle fingers is called "12". A pen held between the thumb and ring finger is in slot "T3".
