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.
the answer is attractive. but i don't see how this is how I draw mine and I use the RHR on the magnetic field between the two wire and I got the force is opposite
Although it is considered unwise to judge a book by its cover, a book's cover is still useful for finding the direction of the cross product ##\mathbf{A}\times \mathbf{B}## between two given vectors. Being able to read is all that is needed. Here is a detailed procedure.
Step 1. Move one...
I built this DIY generator on the thought that the flux from two north poles of a magnet would be attracted to an iron core of a toroid coil. I wrapped the 4 inch OD toroidal coil with about 700 turns of 27 awg wire. The toroid coil is stationary with the magnetic flux rotating around the coil...
Ok I’m trying to understand the right hand rule in relation to electromagnets. Since I’m a visual learner I made myself a little diagram. Is my little diagram correctly showing the flow of electrons relative to the magnetic poles?

OK so a wire with a current creates a b field in accordance with the right hand rule. Now moving charge will feel a force (if its moving in the correct direction) while stationary charges will not feel a magnetic force.
What I am curious about is if we move the wire itself, will a stationary...

If an electron is moving in a circle in a magnetic field, it produces a magnetic field in accordance to the right hand rule. If a proton is moving in a circle in a magnetic field, would it produce a magnetic field in accordance to the left hand equivalent to the right hand rule.
I know that the right hand rule applies for induced currents, and the left hand rule is for motors, but why? It doesn't seem to connect with any other physics laws and is very counter-intuitive that the current will flow in one direction rather than the opposite direction if both are...
