# A Magnetic Field Direction At The Point Of Vector

This post categorized under Vector and posted on August 6th, 2018.

A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials. In everyday life the effects of magnetic fields are most readily encountered with nearby permanent magnets which pull on magnetic materials (such as iron) and attract or repel other magnets.Magnetic fields surround Earths magnetic field also known as the geomagnetic field is the magnetic field that extends from the Earths interior out into vectore where it meets the solar wind a stream of charged particles emanating from the Sun.Its magnitude at the Earths surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss). Approximately it is the field of a magnetic Equation [1] states that the magnitude of the magnetic field decreases with distance as 1R from the wire. The Magnetic field is also directly proportional to the current I.The Magnetic field is a vector quanvectory like the Electric Field. The magnitude of the magnetic field is given by Equation [1] and the direction doesnt point away towards or in the same direction

Electromagnetic waves are made up of Electric Fields (often called the E-field) and Magnetic fields (also known as H-fields). What is an H-field The H-field is a vector quanvectory (has a magnitude and direction) and is measured in AmpsMeter [Am].Geomagnetic field Geomagnetic field magnetic field vectorociated with the Earth. It primarily is dipolar (i.e. it has two poles these being the north and south magnetic poles) on the Earths surface. Away from the surface the dipole becomes distorted. In the 1830s the German mathematician and astronomer CarlJun 02 2016 The earths magnetic field has been existing for at least 3.4 billion years thanks to the low heat conduction capability of iron in the planets core. This is the result of the first direct measurement of the thermal conductivity of iron at pressures and temperatures corresponding to planetary

The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge. It is a useful concept in atoms and molecules where the effects of charge separation are
