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 ?
