We moved the probe with an increment of 0.5 cm using a linear track, the reading was recorded in different regions of the coil until the Hall probe is completely out of the coil.

Field strength vs radial distance from the center of toroid. From here we can roughly see that the field strength is the largest at the edge of the inner coil and decreases exponentially thereafter. When r is smaller than a, field is a minimum and once it gets to the middle region, it shoots up to...
