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.

Directionality of traffic flow by jurisdiction Countries by direction of road traffic, c. 2020 Left-hand traffic Right-hand traffic No data Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side or to the right side ...
The system is widely used in countries with right-hand traffic, including most European countries. What varies, however, is the prevalence of uncontrolled intersections. In some countries, the right of way at virtually all but the most minor road junctions is controlled by the display of priority vs. stop / yield signs or by traffic lights, while in others (such as France) priority-to-the ...
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 ...
Traversal using right-hand rule (). One effective rule for traversing mazes is the Hand On Wall Rule, also known as either the left-hand rule or the right-hand rule.If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the solver is guaranteed not to get lost and will reach a ...
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.
A right-hand rule is one common way to relate three principal directions. For many years a fundamental question in physics was whether a left-hand rule would be equivalent. Many natural structures , including human bodies, follow a certain " handedness ", but it was widely assumed that nature did not distinguish the two possibilities.
The hand-count rule was passed on Sept. 20 by a pro-Trump conservative majority of Georgia's election board, who said they were attempting to make the Nov. 5 election more secure and transparent.
