FBI mnemonics. 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 ...
The misdirection in this riddle is in the second half of the description, where unrelated amounts are added together and the person to whom the riddle is posed assumes those amounts should add up to 30, and is then surprised when they do not — there is, in fact, no reason why the (10 − 1) × 3 + 2 = 29 sum should add up to 30.
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. 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.
In Western esotericism, left-hand path and right-hand path are two opposing approaches to magic. Various groups engaged with the occult and ceremonial magic use the terminology to establish a dichotomy, broadly simplified as (malicious) black magic on the left and (benevolent) white magic on the right. [1] Others approach the left/right paths ...
In electromagnetism, Fleming's right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings. When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric ...
Bias against people who are left-handed includes handwriting, which is one of the biggest sources of disadvantage for left-handed people, other than for those forced to work with certain machinery. About 90 percent of the world's population is right-handed, [1] and many common articles are designed for efficient use by right-handed people, and ...
The series centers on the life of a preteen girl named Juniper Lee, who lives in Orchid Bay City. Based on Winick's adopted hometown of San Francisco, California, the city is a hub for magical activity and is filled with various monsters and demons, both good and evil.
Left-hand–right-hand activity chart. Appearance. hide. is an illustration that shows the contributions of the right and left hands of a worker and the balance of the workload between the right and left hands. [1]
