Semi infinite and infinite wire

In summary, A semi-infinite wire is a theoretical construct used in physics and engineering to model an infinitely long wire with a finite length. An infinite wire is a theoretical construct used in physics and engineering to model a wire with an infinite length. The main difference between a semi-infinite wire and an infinite wire is the length. Semi-infinite and infinite wires are used in many practical applications, such as modeling electrical circuits, analyzing electromagnetic fields, and designing antennas. However, they are idealizations and do not accurately represent real-world conditions.

I am studying magnetic field and I could not distinguish the difference of semi-infinite and infinite wire. Can someone please explain briefly the difference of these two? Thank you.

I would imagine an infinite wire would run from -infinity to +infinity.
A semi infinite wire would be from some value to +/- infinity.

infinite means no end on both sides semi infinite means which is fixed at one point and other point is not fixed eg line infinite and ray semi infinite
 

What is a semi-infinite wire?

A semi-infinite wire is a theoretical construct used in physics and engineering to model an infinitely long wire with a finite length. It is often used in calculations and simulations to simplify complex systems.

What is an infinite wire?

An infinite wire is a theoretical construct used in physics and engineering to model a wire with an infinite length. It is often used in calculations and simulations to simplify complex systems.

What is the difference between a semi-infinite wire and an infinite wire?

The main difference between a semi-infinite wire and an infinite wire is the length. A semi-infinite wire has a finite length, while an infinite wire has an infinite length. Additionally, a semi-infinite wire is often used to model a real-world system, while an infinite wire is used to simplify calculations and simulations.

How are semi-infinite and infinite wires used in practical applications?

Semi-infinite and infinite wires are used in many practical applications, such as modeling electrical circuits, analyzing electromagnetic fields, and designing antennas. They are also used in theoretical physics to study wave propagation and other phenomena.

What are the limitations of using semi-infinite and infinite wires in calculations and simulations?

While semi-infinite and infinite wires are useful in simplifying complex systems, they are also idealizations and do not accurately represent real-world conditions. Additionally, they may not take into account factors such as resistance, capacitance, and inductance, which can affect the behavior of a real wire.
