Magnetic Dipole Moment Using Halbach Arrays

In this demo, we continue our experiment with Halbach Arrays and show how you can practically measure the Dipole Moment using the setup!

Hi ;I want to do a project using arduino and magnetic field effect(halbach etc...). I need to move the toy vehicles that I will use in the project and make them go to the correct positions. IS this possible with arduino and low DC Voltage ? or no way Thanks.

What is the material that prevents iron from being attracted to magnets?

Would this array configuration make a better alternator than traditional PMA's?

How about running a vertical electrical field to create some kind of vortex field? If so would it be DC and would you have to match the magnetic field in strength? Thanks

what determines the "strong side" and the "weak" side??? wouldn't the poles be pointing the "other way" if the array was turned upside down or turned like a wheel?

Is there an easy-to-understand way to go from torque or movement, to volts and amps, when there's a wire coil and iron core involved? I'm wondering about the math behind using a hallbach ring and moving coils for a wind generator, and I want to somehow calculate the sizes of things I need, and the output I can expect, based on my known input (rotational) torque and speed. What I've gleaned so-far, is the the number of windings of the wire determines the voltage - but I've not found any examples or units or info about the scale of these things (e.g. "double voltage with double windings" is fine, but *what* is the "starting" voltage?)

I feel like that burp trying to surface in a sea of magnetic waves bruh.

That's not a halback array. Ur magnets gradually advance the vector around a circle. Halback arrays concentrate the vectors. What u have is the equivalent to a virtual torroid coil.

Sorry but wtf is the point in this video
