Why is the b field inside a thick toroid largest along inner edge and smallest along outer edge?

B = u0NI/L
where NI = amp turns, and L is circumference of field line, which is shorter around the inner edge.
You are correct that the average B field is the same as the central field in the toriod. The lower B field at the outer edge averages out with the higher B field at the inner edge.Maxwellkid said:If u investigate insde the toroid, don't the outer edge cancel out the inner edge so that the b field is equal both along inner and outer edge?

This is a good question. Already I stated in an earlier post that the azimuthal B field in the toroid is given byMaxwellkid said:then, why does it state in my book that the b field along inner edge of the toroid is greater than the b field along outer edge?
A toroid is a three-dimensional geometric shape resembling a donut. In science, it is commonly used in the construction of transformers, solenoids, and other electromechanical devices. Its shape allows for a compact and efficient design for these devices.
The magnetic field inside a toroid is created by the flow of current through the toroid's coils. The shape of the toroid allows for the magnetic field lines to be confined within the coil, resulting in a stronger magnetic field along the inner edge.
The thickness of a toroid does not directly affect the strength of the magnetic field. However, a thicker toroid may have a larger number of coils, resulting in a stronger magnetic field due to the increased flow of current.
Yes, the direction of the current will determine the direction of the magnetic field in a thick toroid. The right-hand rule can be used to determine the direction of the magnetic field by pointing the thumb of the right hand in the direction of the current and curling the fingers towards the center of the toroid.
The magnetic field inside a thick toroid and a solenoid are similar in that they both have strong magnetic fields along their inner edges. However, the magnetic field inside a toroid is confined within the toroid's coils, while the magnetic field inside a solenoid extends outside the coil.
