Abstract:
1. A wear member comprising: a body having at least a first accommodation defined therein; said body having a width, a breadth and a thickness, each of said width and breadth being greater in magnitude than said thickness; at least a first magnetic member, said first magnetic member being seated in said first accommodation; said body having a first portion, a second portion, and a peripheral wall; said first portion being made of a first material; said first portion extending predominantly width-wise and breadth-wise, and overlying said first magnetic member; said second portion underlying said first magnetic member; said peripheral wall extending about said magnetic member; said first material being a non-magnetizable, non-brittle, consumable wear material; said first material having a first modulus of elasticity; said magnetic member including magnetic material, said magnetic material having a modulus of elasticity; said first modulus of elasticity of said first material being at least an order of magnitude smaller than said modulus of elasticity of said magnetic material of said first magnetic member; said second portion being magnetically transparent; said body defining a footprint of said wear member for seating on a magnetically attractive substrate, and, when in use, said second portion extends between said first magnetic member and the magnetically attractive substrate, and maintains a stand-off distance therebetween; said first magnetic member has a first magnetic pole and a second magnetic pole; said first magnetic pole is proximate to said second portion; and said second magnetic pole is distant from said second portion.
