The compass is a tool that helps the user navigate using the Earth's magnetic poles by using a magnetized pointer that reacts to magnetic fields. Since a compass can be used to calculate a heading it quickly improved the safety and efficiency of travel, especially ocean travel. It has only recently been replaced by Global Positioning Systems. It works by indicating the direction of the magnetic north of a planet's magnetosphere. Generally the face of a compass highlights the north, south,...
An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...
