... machine. Sawing with circular saws having carbide-tipped blades is widely used as a method of preparing stock because sawed ends are usually in much better condition than sheared ends. The principal disadvantage of sawing is the loss of metal because of the kerf. In addition, if the burrs left by...

Basically, magnetization is derived from the circular magnetic field generated when an electric current flows through a conductor. The direction of the field is dependent on the direction of current flow...
