Tensile Strength, the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. For example, if a metal rod one square inch in cross section can withstand a pulling force of 1,000 pounds but breaks if more force is applied, the metal has a tensile strength of 1,000 pounds per square inch.
Magnets are used in all kinds of applications, but do you ever wonder exactly why it sticks to certain metals? Find out the answer to this and other questions as we explore exactly how magnets work.
It begins with an unassuming "H" and ends in crazy elements that you've likely never heard of. But the periodic table, encapsulated on a mere sheet of paper, can be a scientist's best friend and a testament to our human drive to organize the world.
