Cabbage, broccoli, and cauliflower are in the same plant family, so they will use similar nutrients, depleting the soil faster of those nutrients (they are heavy feeders). Also, they will attract the same pests and diseases, so keep an eye out. We've revised the text in the article so that it is clearer.
Introduction. Magnets have north poles and south poles. These attract each other. But two north poles will repel each other, as will two south poles. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Most other metals, like aluminium, copper or gold, are not magnetic.
All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.Each of these metals have the special property of being able to be magnetized uniformly. When we ask how a magnet works we are simply asking how the object we call a magnet exerts itâs magnetic field.ll magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.
