## The Attempt at a Solution

Because of the external magnetic field ##\vec B_0 ## , a uniform magnetization will be in the direction of external magnetic field.

Because off this uniform magnetization, there will be a uniform magnetic fied in the direction of magnetization.

So, this implies that ##\vec H ## will be uniform and in the direction of the external magnetic field.

Let's take direction of external magnetic field along z - axis.

Take a square loop such that its two sides is along the z - axis and the other two are along the x-axis.

let's take one z-axis side at infinity, then Ampere's law gives ## \vec H = 0 ##, which gives ## \vec B = \vec M = 0##.

Is this correct ?
