What produces a magnetic field?

Answer 1

The outer electrons in a metallic bar all allign themselves within the bar to generate a single field with magnetic properties. The element, Iron, have this property but it is also seen in other metals in the Periodic Table.

Answer 2

All electrical currents generate a magnetic field.

It is not known exactly how the Earth's magnetic field is formed.

ans2. All magnetic fields are caused by the movement of electrons. Even those of permanent magnets, for there it is the alignment of the spin of the electrons that creates the field.

In the case of the Earth, the magnetic field is believed to be caused by electrical currents running roughly parallel to the Equator. There may well be several current paths, and they may vary, and what we observe is the net effect of these currents.

A few % of the field is caused by the impact of the Solar Wind, a stream of charged particles blowing from the Sun.

Answer 3

Magnetic fields can be formed by a moving electrical current or by quantum properties of certain elements. Earths magnetic field is mostly created by moving electrical currents in the outer core, which is composed of conductive liquid iron.

Answer 4

A magnetic field is produced by moving electric charges. This can occur in the form of electric currents flowing through conductors, such as wires, or in certain materials like iron where the electrons are already in motion due to atomic-level effects.

Answer 5

a moving electric field, in other words an electric current.

Answer 6

Well the poles of south and north connect which means the poles connected

Answer 7

magnets
