Detailed explanation-1: -They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
Detailed explanation-2: -Magnetism is a physical properties on the macro-level. Common measurements of magnetism are the field strength, H, and the magnetic flux, . On a micro-level, magnetism is associated with the atoms that make up materials and is still not completely understood.
Detailed explanation-3: -The ability to conduct heat (thermal energy) or electricity is a physical property which can be tested.
Detailed explanation-4: -The mass of an object is related to its weight, but mass and weight are not the same. Mass (M) is the measure of the amount of matter in an object. Mass is measured in grams (g). Mass is measured on a balance by comparing the object against other objects with known masses.
