Amagnetic field of 0.90 t is aligned vertically with a flat plane. the magnetic flux through the plane is 7.3 × 10^-3 wb. what is the inside diameter of the pipe? show all work and include units of measure

0.10 m

Explanation:

The magnetic flux through the plane is given by

where

B is the magnetic field intensity

A is the area of enclosed by the pipe

In this problem, we know

is the flux

B = 0.90 T is the magnetic field strength

Solving the equation for A, we find the area enclosed by the pipe

We know that the area is given by

where r is the radius. Solving for r, we find the radius:

And so the diameter is twice the radius:
