The discussion revolves around calculating the magnetic field at the center of a circular current loop using Ampere's law. The original poster presents an equation and expresses confusion regarding the application of Ampere's law in this context.
The discussion is exploring the limitations of Ampere's law in this context, with participants providing insights into when the law is applicable. There is no explicit consensus yet, but the conversation is delving into the reasoning behind the use of Ampere's law.
Participants note that Ampere's law is valid in general but may not yield direct relations for certain configurations, such as a circular current loop. The discussion highlights the need for specific conditions to apply the law effectively.
The circuital law helps to determine magnetic field due to current in case of solenoid ,toroid and straight current carrying wire. Why does it fail for circular current loop?Qwertywerty said:You can not use Ampere's law to find the magnetic field at any point in the loop - nor at center , nor at any other point inside the loop .
Firstly , Ampere's law , is obviously valid always .dk_ch said:The circuital law helps to determine magnetic field due to current in case of solenoid ,toroid and straight current carrying wire. Why does it fail for circular current loop?
