This is because the hot rolling process causes the grains of the metal to become elongated and aligned in the direction of rolling. This alignment makes it more difficult for magnetic fields to pass through the metal, resulting in a lower permeability.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Option A is incorrect because hot rolled sheets do have a permeability, even though it is low.<\/li>\n<li>Option C is incorrect because hot rolled sheets do not have a high permeability.<\/li>\n<li>Option D is incorrect because hot rolled sheets do have a value of permeability, even though it is low.<\/li>\n<\/ul>\n<p>I hope this helps!
