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?
A magnetic field at the centre of a circular current loop is a region in space where a magnetic force is exerted on any magnet or moving charged particle. It is caused by the flow of electric current through a circular loop of wire.
The direction of the magnetic field at the centre of a circular current loop can be determined using the right-hand rule. If you point your right thumb in the direction of the current flow, the direction in which your fingers curl represents the direction of the magnetic field.
The strength of the magnetic field at the centre of a circular current loop is affected by the magnitude of the current flowing through the loop, the number of loops in the wire, and the distance from the centre of the loop. Increasing any of these factors will result in a stronger magnetic field.
The magnetic field at the centre of a circular current loop is strongest at the centre and decreases as you move further away from the centre. This is because the distance from the centre affects the strength of the magnetic field, with the field becoming more spread out and weaker as you move away.
The magnetic field at the centre of a circular current loop has various applications in everyday life, including in electric motors, generators, and MRI machines. It is also used in compasses for navigation and in particle accelerators for scientific research.
