# What is the line integral of between points i and f in FIGURE EX29.20?

The magnetic field integral is

See the step by step solution

## Step 1: Given information

We have given,

Magnetic field =

we have to find the magnetic field integral.

## Step 2: Simplify

Apply ampere's law on wire. since wire is along with the magnetic field in the same direction then

from the diagram

Then
