The point at which the net magnetic field will be zero, the magnetic field due to first wire must be equal and opposite in direction to the magnetic field due to the second wire.
Magnetic field between two the parallel wires
The magnetic field between two parallel wires is determined as follows;
B = μI/2πd
where;
- B is magnetic field strength
- I is the current in one wire
- d is the distance between the parallel wires.
From the formula above we can conclude that, the point at which the net magnetic field will be zero, the magnetic field due to first wire must be equal and opposite in direction to the magnetic field due to the second wire.
