What is the five hand rule?
I need to know what direction the wire is going to move

Doc Al said:I recommend that you learn to use the right hand rule to find the force on a current-carrying wire in a magnetic field.
Looks like you do it differently. (I'm willing to use [itex]f[/itex] instead of [itex]\nu[/itex] for frequency, but don't mess with my right hand rule! )Adrian Baker said:Right hand rule?? Don't you mean left hand rule, or do we do this different in the UK?
So does the right hand rule. I use the right hand rule whenever a cross product is involved. To find the direction of [itex]\vec{A}\times\vec{B}[/itex], just curl the fingers of the right hand from A to B along the shortest arc. The thumb points in the direction of the cross product. (At least that's the way I do it. Check the second of the links I posted for live action video of the right hand rule in use.)Left hand rule gives direction of the force on a wire in a magnetic field where the current direction is CONVENTIONAL current flow, not electron flow.
Apparently the right hand rule and your left hand rule give the same answer. Good thing, I suppose!In the case above, the wire moves OUT of the PC screen towards you.
Again, a deficit of having never finished high school. I was taught only the left-hand rule. (ie: thumb in direction of current flow puts fingers in direction of magnetic field and vice versa) Jeez, but I love learning new stuff here!z-component said:The left hand and right hand rules are both taught in my school.
AcEY said:No it doesnt, in the UK we drive on the correct side of the road, whilst you americans drive on the other side just because its the opposite of the english (do to the revolution etc...)
That works fine until you run into a left-hand thread and strip the thing.T@P said:this is really a difficult explanation of something very simple. and actually clockwise and c-clockwise is inherent if you want to know which way the screw goes, so you don't need to make funny hand symbols as you do it.
oh and this ties in nicely with right tighty - lefty loosey ;)
Not if it's dyslexic.Adrian Baker said:Clockwise is confusing too - if you are the clock!
To a clock the hands go anti-clockwise.
The Five Hand Rule is a simple and effective method used to identify the direction of current flow in a wire. It involves using five fingers of your hand to represent the five main components of a circuit: power source, load, switch, ground, and wire.
To use the Five Hand Rule, hold out your hand with your four fingers pointing in the direction of the flow of current (from positive to negative) and your thumb pointing in the direction of conventional current flow (from negative to positive). The palm of your hand represents the wire, with the thumb acting as the positive end and the fingers as the negative end.
The Five Hand Rule is used to quickly and easily determine the direction of current flow in a wire. This information is important in troubleshooting circuits and understanding how different components are connected in an electrical system.
Yes, the Five Hand Rule can be used for all types of circuits, including DC (direct current) and AC (alternating current) circuits. It is a universal method that applies to any type of electrical system.
The Five Hand Rule is a simple and general method that may not be accurate in certain situations, such as when dealing with complex circuits or circuits with multiple power sources. In these cases, more advanced techniques and tools may be necessary to accurately determine wire direction.
