•PoutsideP,holeP,insideFor a torus – think doughnut or bagel – we consider N turns wrapped around the donut, carrying a current I (the wires arestill tightly packed, even though it doesn't appear so in the picture!)Using the ideas of the field outside a solenoid, what should be the magnetic field atpoint Phole, in the hole, and point Poutside, outside the toroid?b. From symmetry, what should be the direction of the magnetic field at point Pinside,inside the toroid?Use Ampere's Law to find the magnetic field inside a toroid, as a function of r.a.С.

In the problem shown below, in finding the magnetic field at a certian point in the z-axis, I assumed that we have to break it up into infinitisemal loops, however, I would like to be advised on how the thickness factors into it. Thank you
