Right hand rule Definition and 116 Threads

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? Also does the core and helix being slightly curved affect the...

Hello. I am trying to do a basic experiment to demonstrate I⊗β≈ƒ or current cross magnetic field results in a force perpendicular to the plane of the other two. But every time I test this out, it appears I get a force in the same direction as the magnetic field. Here is my experiment: Strong...

What does right hand rule torque mean in real life? engine crankshaft produce torque,if apply right hand rule to crankshat that will mean that torque is act in crankshaft axiis of roatation,which mean axials berings will have huge load on it,,that is not the case in reality,axail bering don't...

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...

Suppose we are in communication with aliens who live in a different universe. I know, that's impossible, communication requires the exchange of mass or energy, which implies that we live in the same universe. But suppose it is true. I am wondering, can we and the aliens, via this communication...

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...

(First, I am aware there is no cross product in higher dimensions. I am aware of differential forms. I am aware of the problems with the cross product. I know enough to know what I don't know. but set all that aside.) With that, could someone help me, by properly phrasing the cross product...

Hi there, I attached an image of a basic linear motor. I'm a little confused if I use the right hand rule or left hand rule. I did it both ways and I think the left hand rule is the only rule that allows for a force being applied to the right. I assume the current is going down rather than...
