# Current and magnetism relationship

### Understanding the Relationship Between Magnetism and Electricity

Yes, there would be an electromagnetic force acting between the two current carrying iron bars. This is similar to the way the unit the ampere is. Intro to Magnetism: Sources of Magnetic Fields, Magnetic Fields and Forces A current traveling through a loop of wire creates a magnetic field along the axis of . A French scientist named Andre-Marie Ampere studied the relationship He discovered that magnetic fields are produced by moving charges (current).

## Magnetic Field Basics

Relation between Magnetism and Electricity at Atomic Level There is a relationship between magnetism and electricity, as both use positive and negative forces. Every atom consists of electrons which are negatively-charged particles, protons which are positively charged, and neutrally-charged neutrons.

Just because these two different charges exist in the atom, the phenomena of magnetism and electricity occurs. Electricity, in its static form, is nothing but an imbalance of positive and negative charges.

When an electron is moving round the nucleus, a loop of electric current is formed. This in turn, results in the formation of a magnetic field within the electrical loop. It is believed that this is the basis of the magnetic properties found in different types of materials. Properties of Electric and Magnetic Fields Electric field is the area surrounding a charged particle, where if any other charged particle makes an entry, it will experience a force.

## Understanding the Relationship Between Magnetism and Electricity

Magnetic field is the area surrounding a magnet, where apparent magnetic influence can be found. These two fields are interrelated. Noted Scottish physicist and mathematician James Clerk Maxwell derived some equations to explain the relationship between the properties of electric and magnetic fields, as well as their geometric relations involving the circuits.

The derivations of his equations are described as follows: Any change in an electric field would result in the formation of a magnetic field. On the other hand, changing magnetic fields would yield electric fields.

When an electric field is constant, it does not produce magnetic fields. Similarly, a magnetic field with a constant value would never produce any electric field. Magnetic monopoles do not have any existence.

This means that no magnet can have only a north pole or just a south pole. In the similar way, the flow of electricity or charged particles especially free electrons in a particular direction is called current electricity or electric current. Magnetism is a type of attractive or repulsive force that acts up to certain distance.

The distance up to which this attractive or repulsive force acts is called magnetic field. Magnetism is caused by the moving electric charges especially electrons. When two magnetic materials are placed close to each other, they experience an attractive or repulsive force. We know that all the objects in the universe are made of small particles called atoms. The atoms consist of sub atomic particles such as electrons, protons, and neutrons. The strong nuclear force between the protons and neutrons makes them stick together to form nucleus.

The electrons present in the atom revolve around the nucleus because of the electrostatic force of attraction between the electrons and nucleus.

### Relation between electricity and magnetism

The electrons revolving around the nucleus also rotates or spins around its own axis. Because of this spinning of electrons, magnetic field is produced. If the majority number of electrons in the atom spins in the same direction, a strong magnetic field is produced.

The direction of the electrons spin determines the direction of magnetic field. On the other hand, if the equal number of electrons in the atom spins in the opposite direction, the spinning speed of the electrons cancels out.

Thus, the magnetism also cancels out. Relationship between electricity and magnetism In the early days scientists believed that, electricity and magnetism are two separate forces.
