First finger is for the direction of the magnetic field, second finger is for the direction of the current and the thumb thus points in the direction of the force.

And you shall not be a dummy again!

The middle finger is for B-Field
The thumb is reserved for Force
The index finger is for current
You hold those fingers in this pose
If two fingers match their vectors
You'll know where the third one goes!

If we point index finger of our right hand in the direction of ā and middle finger in direction of c̅ then thumb points in the direction of their cross product ā × c̅, which is the vector that is perpendicular to both ā & c̅ and thus normal to the plane containing them.

The only hand rule I need to know is trig exact values, what would I do without it (I pretty much know them but it helps)

John Fleming is dead long time ago but his hand is still alive 😬

I used this rule when I studied electromagnetism.

The thumb is the magnetic force
The index is the speed
and the middle is the magnetic field

Flemming's right-hand rule for motors.
The left hand is for generators

Yeah, I’d love an actual video on this, but I guess this is fine?

Electric field, Magnetic field and Poynting vector of an electromagnetic wave

[tositioo]

in Russian school, we were taught the "rule of the left hand", where the magnetic induction vector enters the palm, four fingers are located in the direction of the current, and the thumb shows the strength of the magnetic induction

the rule turned out to be: the left hand for tasks related to the magnetic field, and the right hand for tasks with an electric field

I prefer to curl my fingers and stick out my thumb, but this works too.

Bro, im glad i never have to do this again. (Im waiting until it sneaks its way into my uni corse)

[peterchan]

I don't get this at all. Is this a Maths channel or an FBI channel?

Keep ur each finger mutually perpendicular

[whoff]

I thought here to hear sth. about math
but 3-fingers-rule is about physics ?
