What is Right hand rule: Definition and 116 Discussions
In mathematics and physics, the right-hand rule is a common mnemonic for understanding orientation of axes in three-dimensional space.
Most of the various left-hand and right-hand rules arise from the fact that the three axes of three-dimensional space have two possible orientations. One can see this by holding one's hands outward and together, palms up, with the fingers curled, and the thumb out-stretched. If the curl of the fingers represents a movement from the first or x-axis to the second or y-axis, then the third or z-axis can point along either thumb. Left-hand and right-hand rules arise when dealing with coordinate axes. We can use this to find the direction of the magnetic field, rotation, spirals, electromagnetic fields, mirror images, and enantiomers in mathematics and chemistry.

Does anyone know of a good site that explains this rule? I just don't get it at all. Better yet, is there some way you can know the direction of the magnetic field without doing it
I have learned just about the right hand rule in vector cross product. How is this proved? Can anybody give an example where the cross product plays an important role and where the vector cross product formula is obeyed?
Our professor just told us that the torque due to a force acting on a body...
hi i have a few general questions on the right hand rule,
1. if a charged particle enters a magnetic field going from bottom left to top right at an angle of 45 degrees, and the direction of the current is vertically up how do we determine the force using the right hand rule?
2. a wire which...
If a metal ring is places near a solenoid, what is the direction of the induced current in the ring for the following cases
a. At the instant the swithc in the circuit containing the solenoid is thrown closed.
b. After the switch has been closed for several seconds.
c. At the instant...
Hello.
I have a question about RHR #2 (Force in a conductor).
If IL X B = F and
If the fingers represent the direction of the current, the thumb represents the direction of the force and the palm is the direction of the magnetic field, how come the magnetic field can be at an angle...
The electrons in the beam of a television tube have a kinetic energy of 2.40×10–15 J. Initially, the electrons move horizontally from west to east. The vertical component of the earth’s magnetic field points down, toward the surface of the earth, and has a magnitude of 2.00×10–5 T.
Just when...
Indicate the direction of the electric field between the plates of the parallel plate capacitor shown in the drawing if the magnetic field is decreasing in time. Give your reasoning
if the magnetic field is decreasing, so is the flux, so mr. lenz says the induced magnetic field must be out of...
Im having a really hard time with these...I have three different problems so here they are..
Situation one: Particle moving up, field moving to the right. Thus the force has to be either into or out of the page so to speak because it has to be perpendicular. Through the right hand rule I...
A vertical wire carries an upward 3 amp current. you are 1.2 m from the wire in a direction 20 deg north of east. You experience a magnetic field ( due to the wire) that is directed in what direction? Yes, you do use the right hand rule, but what direction does the right hand rule tell you?
