The magnetic force’s magnitude on the wire’s portion between x = λ and x = 0 is iλB.

Explanation:

Given:

Flowing electric current via the wire = i

In the x−y plane, along the curve, the wire is kept, y=A \sin 2 \pi \lambda x

In the z direction, magnetic field (B) exists.

We must see that on the wire portion, the magnetic force between x = λ and x = 0.

Magnetic force is shown as

F \rightarrow=i l \rightarrow \times B \rightarrow

For a small element dl,

d F \rightarrow=i d l \times B \rightarrow

On the full wire, the effective force is equal to the starlight wire’s force of length λ positioned along the x axis.

So,

F=i B \int 0 \lambda d l

\Rightarrow F=i \lambda B
