... GRADE-LEVEL CONCEPT 2: An unbalanced force acting on an object changes its speed and/or direction of motion. GRADE-LEVEL EXPECTATIONS: 1. In order for an object to change its motion, a push/pull (force) must be applied over a distance. 2. Forces can act between objects that are in direct contact, ...

How Relativity Connects Electric and Magnetic Fields
... The mistake was in ignoring the relativistic Fitzgerald-Lorentz contraction, even though the velocities involved are millimeters per second! In the frame in which the wire is at rest, the positive and negative charge densities exactly balance, otherwise there will be extra electrostatic fields that ...

Mainly so because according to the relativistic analysis above, if the wire with current flowing through is neutral (This is what the derivation start from) the wire without current will become electrically charged in lab frame. This is obviously against the ...
