· Separating mixtures using magnets. Magnetism can attract or repel certain materials like iron and steel through an invisible magnetic field. Magnets are made of materials that produce this field and can pull other magnetic objects towards them or repel other magnets. The document then discusses using magnets to separate mixtures by

· Heterogeneous mixes are made up of at least two separate components, ingredients, or phases (any part of a sample that has uniform composition and properties). Mixtures may typically be separated. Phases combine but preserve their chemical identities. Mixtures of multiple states of matter (gas, liquid, solid) are inherently heterogeneous.

Updated on November 05, 2019. Magnetism is defined as an attractive and repulsive phenomenon produced by a moving electric charge. The affected region around a moving charge consists of both an electric field and a magnetic field. The most familiar example of magnetism is a bar magnet, which is attracted to a magnetic field and can attract or
