Two and Three Current Carrying Wire

In summary, the magnetic field is zero at two points in the region between two or three parallel current-carrying wires. These points are located inside the wires and are determined by applying the right hand thumb rule. The magnetic field of the third wire must nullify the magnetic fields of the other two wires in order for the field to be zero at these points.

If there are two or three parallel same direction current carrying wire where are two points there magnetic field is zero? Are those two points inside or outside of wires?

Didnt i explain you there... If you didnt understand that then you must have told me...

Please show some work for christ's sake

Inside.

Lets suppose that the current is moving from left to right. Now apply right hand thumb rule in region B. The mafnetic field of 3 would be coming out of the plane but that for 1 and 2 it would be inside the plane. And it would be near B cause the magnetic field of 3 not only has to nullify the magnetic field of 2 but of 1 also. Same goes for in the region B
 

FAQ: Two and Three Current Carrying Wire

What is the concept of two and three current carrying wire?

The concept of two and three current carrying wire refers to the behavior of multiple wires carrying electric currents in close proximity to each other. When these currents interact, they can create electromagnetic fields and induce forces on each other.

How do the currents in two and three wire systems affect each other?

The currents in two and three wire systems can affect each other through the creation of magnetic fields. These magnetic fields can cause the wires to experience a force, either attracting or repelling each other, depending on the direction of the currents.

What is the difference between two and three wire systems?

The main difference between two and three wire systems is the number of wires involved. In a two wire system, there are only two wires carrying currents, while in a three wire system, there are three wires carrying currents. This can affect the strength and direction of the magnetic fields created.

What factors can impact the behavior of two and three wire systems?

Several factors can impact the behavior of two and three wire systems, including the distance between the wires, the direction and magnitude of the currents, and the type of material the wires are made of. These factors can all affect the strength and direction of the magnetic fields created.

What are some real-world applications of two and three wire systems?

Two and three wire systems have various real-world applications, including electric motors, transformers, and power transmission lines. Understanding the behavior of these systems is crucial in designing and optimizing these technologies for efficient and safe operation.
