Consider that we have a magnet and a magnetometer (a fluxgate magnetometer with a single coil), standing still as shown in fig 1.
In fig 1, the magnetic field measured at the axis z1 of the magnetometer coil is B1.
But if everything (magnet, magnetometer and the axes) was rotating together...
Consider two thin and long, single layered identical solenoids with same DC in them, positioned coaxially. I'm trying to calculate the magnetic force on each solenoid, when there are identical magnetic cores inside them.
As seen in below, I have the general approximation to the force between...
Hello there,
I have a question (two very similar questions) about the time and phase delay between rotating objects. I want to describe two extreme cases here: I would appreciate any helps.
Case 1
Imagine two observers (people with telescopes maybe) in space that are standing thousands of...
What else comes into play between two accelrated charges? Delayed charge distances/potentials? or EM wave momentum?
I will try to fix the image. In the image, the two charges are at the same coordinate of the acceleration axis (with a distance between them on the perpendicular axis). So...
There is a similar thought experiment I imagined to help me begin to understand the Bell's spaceship paradox:
Consider two positively charged spheres, placed side-by-side inside a frame S' with a string stretched to the point where it balances the repulsive electrostatic force between them. For...
