摘要：

According to MIT physicist Frank Wilzcek, Newton's law isn't universally true because it fails for magnetic forces between charged particles. Exploring this claim, a previous column provided an experiment from the Feynman Lectures on Physics where two charged particles were moving at right angles at each other and one of them had an unopposed magnetic force acting on it. Arun Bhattacharyya, in his own derivation, noted that for time-varying fields Newton's third law violates causality, primarily because of a propagation delay. Using a simple example, the present work obtains the exact field solution to demonstrate the violation of the law.
