The difference between left and right (2 Viewers)

[jesterofenglish]

'lo all,

Can someone explain to me (or direct me to a site that can) the difference between the right and left-hand rule (aside from the obvious )

When are you supposed to use which one? I am always getting confused and just end up looking like a complete moron who still gets the wrong answer.

righthand rule for positive charge , left hand rule for negative charge ( electron )

Well i personally always use right hand, if its +vely charged then direcion is out of palm, -ve is out of back of hand... thats about right :S

There are so many variations of the left and right rule, it really depends on the one you learnt.

If its the one that uses the palm as the force then it is as donis said. Thats the one I use or use the right hand always and point the thumb in the opposite direction for a negative charge.

If its Fleming's Left Hand Rule with the thumb and first two fingers like a gun then it is the opposite to what Donis said.

just learn one... don't try and confuse urself

Totally agree Dougie, which is why I use the Right Hand Palm Rule.

I had to look up the other one but to answer Jester's question we need to know which one he uses

 

[jesterofenglish]

I 'learnt' the right hand gun one that looks like your giving ur teacher the finger if the F, B, I is in the right direction . . .

If it is Flemings Left Hand Rule
See web page

You swap hands when it is a negative charge. So left for positive or current, right for negaive.

But check that is the same arrangement you are learning.

As someone said before... just use the right hand...
For a pos change move ur hand in the direction of your palm,
for a neg change move ur hand in the opposite direction in which ur palm is pointing...
Simple!
