what are the similarities between electricity and magnetism?
303996
Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

ELECTROMAGNETIC WAVES Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves.

Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current. In an electromagnetic wave, the electric field and magnetic field are perpendicular to one another.

In metals like iron, the orbital magnetic moment encourages nearby atoms to align along the same north-south field lines. Iron and other ferromagnetic materials are crystalline. ... This is because magnets attract materials that have unpaired electrons that spin in the same direction.

In such a wave, time-varying electric and magnetic fields are mutually linked with each other at right angles and perpendicular to the direction of motion. An electromagnetic wave is characterized by its intensity and the frequency ν of the time variation of the electric and magnetic fields. Electromagnetic radiation.

magnetic circuits The magnetomotive force, mmf, is analogous to the electromotive force and may be considered the factor that sets up the flux. The mmf is equivalent to a number of turns of wire carrying an electric current and has units of ampere-turns.

The inherent characteristic of electromagnetic waves is its frequency. According to Maxwell, varying the electric field gives rise to a magnetic field. An accelerated charge produces a time-varying magnetic field which in turn produces a time-varying electric field.

4) Gravity (mass) is monopolar it always attracts. Magnetism is dipolar; like poles repel while unlike poles attract. 5) All matter has mass therefore contributes to g. While main magnetic field is due to convection currents in the core; it effects on some minerals not all.

The magnetic field from a wire decreases with distance from the wire. Instead of the field being proportional to the inverse square of the distance, as is the electric field from a point charge, the magnetic field is inversely proportional to the distance from the wire.
651895
Electromagnetic waves are formed when electric field couples with magnetic field. The magnetic and electric field are perpendicular to each other.

Electricity is the movement of electric charges, typically electrons. Electromagnetism is an additional force that arises because of special relativity - lengths change when something is in motion. ... Put simply, electromagnetism is a residual electrostatic force that is a consequence of special relativity.

Similarities between magnetic fields and electric fields: ... Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge ...

Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces. Electricity and magnetism are integral to the workings of nearly every gadget, appliance, vehicle, and machine we use.

Gravity is a weak force, but has only one sign of charge. Electromagnetism is much stronger, but comes in two opposing signs of charge. This is the most significant difference between gravity and electromagnetism, and is the main reason why we perceive these two phenomena so differently.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.
