Chapter 29: Q. 20 (page 831)

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

Short Answer

Expert verified

The magnetic field integral is0.07T.m.

Step by step solution

01

Given information

We have given,

Magnetic field = 0.1T

we have to find the magnetic field integral.

02

Simplify

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

∫ifB→dS→=∫ifB.ds=B.L

from the diagram

L=0.52m

Then

B.L=0.07T.m
