What is the line integral of B→between points i and f in FIGURE EX29.21?

Short Answer

Expert verified

The line integral will be 0.

Step by step solution

01

Given information

We have given, a current carrying wire in the magnetic field.

We have to find the line integral magnetic field from i to f.

02

Simplify

Using ampere's law of magnetic field ,

integral=∫ifB.→ds→=∫ifB.ds³¦´Ç²õθ

Since the magnetic field is perpendicular to the wire then,

cos(90)0=0

integral=∫ifB.ds³¦´Ç²õθintegral=0
