Explaining the wire force as between two electrons is used in elementary courses because it seems easy, but it is wrong.
9 Force Between Two Wires. The Need For Relativity Version A: Full Math. W. Blaine Dowler April 21, 2012. Contents. 1 The Success of 19th Century Physics. 2. 2 Mercury’s Orbit. 2.
This force between two current carrying wires gives rise to the fundamental definition of the Ampère: If two long parallel wires 1 m apart each carry a current of 1 A, then the force per unit length on each wire is 2 x 10- 7 N/m.
This increase is seen as a net attractive force between the two wires, usually attributed to the magnetic effect of the currents. We can say that Special Relativity unites the concepts of magnetic and electrostatic force into a single electromagnetic force.
...elds and Gauss’s law, basic magnetic phenomena such as forces between parallel currents, and the rudiments of relativity (including reference frames, length
the force between two current-carrying wires. In this article, the form of the perpendicular nonlinearity N⊥ (in equation 1.1) is. identied using: (i) the relativistic mass increase in CRT experiments; and (ii) con
Key words: Relative Velocity; Weber; Relativity; Electromagnetism. 1. Introduction. Relative-velocity-dependent models in electromag-netism were proposed initially by
[Addendum] To directly answer the original question for the limit $m_2 \to 0$: Of course if $m_2=0$, then the force between the two masses is $0$. But the thing about classical gravity is that the acceleration due to gravity is independent of mass.
Figure 6. Geometry of force between two parallel wires.
There is no force between the wires. 2. Current flows in one wire but not the other.
