Right Hand Rule
The Attempt at a Solution
I can get the magnitude, but cannot get the directions from the RHR. Can somebody make video/explain?
Thanks!

minimario said:It is just the right hand rule...what "sketch" is there?
minimario said:I don't need the magnitude part. I need the direction part... and 3d coordinates are not needed, the right hand rule is.

So point your right thumb in the direction of the current (which way is that?) and your fingers in the direction of the field (which way is that?)minimario said:point thumb in direction of v, fingers in direction of B, then F is direction of palm.
At least answer my questions about directions, or I too will quit the thread. You are not trying very hard to help others help you.minimario said:I cannot bend my hand so far...
... but what direction is the magnetic field geographically?minimario said:Oh, I already know those ones, it's trivial. Current goes toward east, magnetic field is 75 degrees below horizontal...
That's not a geographical direction. N, S, E, W...?minimario said:Would be 75 degrees downward
So point your thumb E, your fingers S and 75 degrees down, with your hand flat. Which way is your palm facing?minimario said:South
Yes. Down at what angle?minimario said:Toward the north and down?
Right.minimario said:15 degrees below the vertical?
Ah yes, I slipped up.minimario said:No, it's not right, according to the answer key: answer says 15 degrees above horizontal in the north south plane
It doesn't depend on the dip angle.minimario said:It's 75 degrees below horizontal, so why is it north instead of south?
The right hand rule is a mathematical tool used in physics and engineering to determine the direction of a vector or the rotation of an object.
To use the right hand rule, extend your right hand with your fingers pointing in the direction of the vector or the axis of rotation. Your thumb will then point in the direction of the resulting vector or the direction of rotation.
The right hand rule is important because it allows us to easily determine the direction of vectors and rotations in 3-dimensional space, which is crucial in many fields of science and engineering such as electromagnetism and mechanics.
Yes, there are different versions of the right hand rule depending on the specific application. The most commonly used version is the cross product rule, which is used to determine the direction of a vector resulting from a cross product of two other vectors.
One tip for remembering the right hand rule is to practice using it regularly. Another tip is to associate the direction of your fingers with the direction of the vector or rotation, and your thumb with the resulting direction. There are also mnemonic devices and visual aids that can help with remembering the right hand rule.
