網頁As a result, a modified Steinmetz equation is proposed. In [3], the approach is further improved, and in [4], a method on how to deal with minor hysteresis loops is presented and some minor changes on the equation are made. The approach of [2]–[4] leads to the 網頁The force per unit length between two stationary parallel wires carrying (steady) currents. 1. is inversely proportional to the separation of wires. 2. is proportional to the magnitude of each current. 3. satisfies Newton’s third law. A) 2 and 3 are correct. B) 1 and 3 are correct.
