A long, straight, hollow conductor (tube) carrying a current has two sections A and C of unequal $$cross-section$$ joined by a conical section B. $$1$$, $$2$$ and $$3$$ are points on a line parallel to the axis of the conductor. The magnetic fields at $$1$$, $$2$$ and $$3$$ have magnitudes $$B1$$ , $$B2$$ and $$B3$$ . Then

Question

Infinity Learn · Accepted Answer

To find the magnetic field outside a thick conductor, the current may be assumed to flow along the axis. As points $$1$$, $$2$$, $$3$$ are equidistant from the axis, $$B1$$ $$=$$ $$B2$$ $$=$$ $$B3$$

A long, straight, hollow conductor (tube) carrying a current has two sections A and C of unequal cross-section joined by a conical section B. 1, 2 and 3 are points on a line parallel to the axis of the conductor. The magnetic fields at 1, 2 and 3 have magnitudes B₁ , B₂ and B₃ . Then
