What are the connections and differences between the electrical properties of rocks and ores, and th

Conductive properties of different substances.

There are many connections and differences between the electrical and magnetic properties of rocks

1.The Law of Electromagnetic Induction: Rocks are affected by electric and magnetic fields in electromagnetic fields, and the laws of electromagnetic induction describe the guessing interaction between electric and magnetic fields.

2.Electromagnetic waves: Rocks also have an effect on the propagation of electromagnetic waves, and the propagation speed and wavelength of electromagnetic waves are related to the electrical and magnetic properties of rocks.

3.Solid State Physics: Both electrical and magnetic properties are related to the solid properties of matter, including crystal structure, density, chemical composition, etc.

Differences:1The physical quantities of electrical properties are different from those of magnetic properties: the main physical quantities of electrical properties are electric charge, electric field, and electric potential, etc., while the main physical quantities of magnetic properties are magnetic field, magnetic moment, etc.

2.The measurement method is different: electrical instruments such as resistivity instruments are usually used to measure the electrical properties of rocks, while magnetic instruments such as magnetometers and magnetic fields are usually used to measure magnetic properties.

3.Different influencing factors: the factors affecting the electrical properties of rocks include charge distribution, conductive materials, temperature and other factors, while the factors affecting the magnetic properties of rocks include rock composition, magnetization state, physical and chemical effects, etc.

4.Different fields of application: The electrical and magnetic properties of rocks have different applications in geophysics, mineral exploration, geological hazards, etc.

Electrical properties are mainly used in groundwater exploration, geophysical exploration and other fields, while magnetic properties are mainly used in geophysics, mineral exploration, drilling and other fields.

Rocks are magnetic because they contain (iron) magnetic minerals, and the types and quantities of magnetic minerals contained in various types of rocks are different, so there are magnetic differences. Observations show that the magnetic properties of rocks vary over a wide range of areas, but with certain regularities (Table. Magmatic rocks are generally more magnetic, ranging from acidic to mafic rocks, along with silica.

The content gradually decreased, the content of ferromagnetic minerals gradually increased, and the magnetic properties of the rock gradually increased. Sedimentary rock.

Magnetic traps are generally weak, and many of them can be considered non-magnetic. The magnetic properties of metamorphic rocks are often related to the rocks before metamorphism. Metamorphic rocks with layered structure with magnetic anisotropy.

The magnetite of non-metallic minerals is weak, and the magnetite of metallic ores has the strongest magnetism.
