Abstract

A magnet or magazine is an object that has a magnetic field. Magnets can also be interpreted as objects with symptoms and properties affecting certain materials around them. Magnetic force is one part of the electromagnetic force, where the other force becomes the fundamental force of nature caused by the movements of charge. Because magnets only attract particular objects, they can also not work or are not stylized, or there can even be a rejection of some particular objects on the magnet. The new generation of transportation is fast, reliable, and safe. In addition, it is also convenient, environmentally friendly, easy maintenance, and supports mass transportation. Magnetic levitation (maglev) trains are among the best candidates that meet these requirements.

Abstract

Seawater temperature ranges from -2 0 c to 300 c. Low temperatures are usually found in seawater around the poles and on the deep seabed. Meanwhile, high seawater temperatures are found in the sea in the Arid area. The Red Sea and Bab El Mandeb have temperatures of about 290 c to 300. Corrosion is a subject matter that concerns various disciplines, or in other words, it connects elements of physics, chemistry, metallurgy, electronics and engineering. This study uses the literature review study method to collect, identify, evaluate the effect of seawater content on the corrosion of the hulls of warships made by PT Pal Indonesia. An effective corrosion control strategy should be selected with the selection of suitable coatings for the marine environment. Hull plating with paint has a special function to protect the construction of the hull, especially those located below the waterline and the construction of the ship above the waterline.
