Question

Two thin long straight conductors have currents 4A and 1A carrying in the same direction which are arranged parallel with a separation of 2 m then find position of neutral point

Answer 1

Answer:

Distance between the conductor is

Answer 2

Answer:

The answer is 0.4 m from the 1A wire

Explanation:

using biot-savarts law, we can just equate the magnetic field by wire 1 at distance x = magnetic field by wire 2 at distance (2-x).
