Electromagnetism mediates the process of the creation of a magnetic field through the introduction of the current in the conductor. If a conductor is electrically charged, it generates magnetic lines of force (Electromagnetism, n.d.)
Electromagnetic Force
An electromagnetic force is a physical interaction that occurs between electrically charged particles, and is considered to be the combination of all magnetic and electrical forces. It is also coined as Lorentz Force acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force (Electromagnetism, n.d.).

RELATIONSHIP BETWEEN ELECTRICITY AND MAGNETISM

As stated in the Uses of Electromagnet with its Applications in the Practical World (2020), Electromagnets are used for various purposes on a day-to-day basis. The following are some uses of electromagnetism:
In Home Appliances
The fundamental operating principle of most electric appliances in the home is electromagnetism. For example the electric fan, electromagnetic induction holds the motor spinning in an electric fan, which causes the blades to rotate.
In Medical Field
Electromagnets are also used in medical applications. The MRI scan, which stands for Magnetic Resonance Imaging, is an electromagnet-based system. With the aid of electromagnetism, the computer will scan all of the tiny details in the human body.
In Communication Devices and Power Circuits
The mobile phones and telephones we used to make long-distance calls may not have existed without electromagnets. Cell phones and telephones are extremely useful due to electromagnetic waves and signal interaction.
In Memory Storage Devices and Computer Hardware
The data in e-book gadgets and phones are stored in the electromagnetic format in the form of bytes and bits. A magnetic tape, which operates on the principle of electromagnetism, is also included in the computer hardware. Even in the olden days’ electromagnets had a huge role in the data storage of videocassette recorder and videocassette player.

Amongst all the kinds of magnetism, only Ferromagnetism is considered strong. According to Jim Lucas (2015), ferromagnetism produces permanent magnets. These are initially distinguished in a type of natural iron ore called magnetite, hence its name. Aside from iron, metals such as nickel, cobalt, and samarium also contain ferromagnetic properties. Moving on to the other kinds of magnetism which are Diamagnetism and Paramagnetism. In 1778, Anton Brugnams discovered Diamagnetism. As stated by HyperPhysics (n.d.), diamagnetism is due to the electron's orbital motion generating tiny current loops that tend to produce weak magnetic fields. Bismuth and Pyrolotic carbon are examples of materials that have diamagnetism properties. Meanwhile, Paramagnetism is when a matter showcases short-term magnetic properties when placed in a magnetic field and eventually comes back to its non-magnetic state once the external field is eliminated. It is also important to take note that this phenomena is only evident on extremely low temperatures. (Marsh, D., n.d.)

The force that enables two electric currents to either attract or repel is called Magnetism. (Stern & Pedro, 2001) In an article by Christopher Baird (2019), he stated that magnetism  is just a part of electromagnetism which deals with magnets, magnetic fields, and magnetic forces. The movement of electrically charged particles stimulates this phenomena and varies depending on the magnitude of the charge, strength of magnetic field, and the velocity of the particle. On a similar note, magnetic field sources are always dipolar, meaning they have a north and south magnetic pole which attracts when they are opposite (North and South) and repels when they are alike (North and North or South and South), as stated by Joseph Becker (n.d.) This leads to toroidal field, because the direction of the field exits from the north pole and enters through the south.

Relationship between Electricity and Magnetism

The movement of electric charges generates a magnetic  field whereas it causes the production of electric currents (Helmenstine, 2018). Instances presented by Learning A-Z in magnetism - the production of charged particles in a wire due to a spinning magnet encircling it- correlates it to electricity- an electric field is present on a charged wire encasing a piece of metal. Furthermore these two are distinct components equating to the force of electromagnetism. The relationship of which was discovered by Danish physicist Hans Christian Oersted in 1820 while presenting an experiment during his lecture, he yielded a definite motion of a compass needle in response to the passing of an electric current through a metal wire suspended above the magnetic compass (Electromagnetism, n.d.) Moreover,  in 1873 James Clerk Maxwell published ‘A Treatise on Electricity and Magnetism’ describing this phenomena, with key takeaways such as the repulsion of like electric charges, and attraction of the unlike charges, similar to magnetic poles which always exists as north-south pairs. Moreover electric currents on a wire induces a magnetic field around it, in which its direction depends upon the course of the current.

According to BrightRidge (n.d.), there are two kinds of electricity: static electricity and current electricity. Static electricity is made by rubbing together two or more objects and making friction while current electricity is the flow of electric charge across an electrical field. Static electricity happens when there is an imbalance of positively and negatively charged atoms. The result of a build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. A good example of this is lightning. Current electricity, on the other hand, is the rate of flow of electrons or a constant flow of electrons. It is produced by moving electrons and it is measured in amperes. Unlike static electricity, current electricity must flow through a conductor, usually copper wire. There are two kinds of current electricity: direct current and alternating current. Direct current is where electrons move in one direction and the strength of its electric current in Amperes does not change. Batteries produce direct current. On the other hand, alternating current is where the electrons flow in both directions. Powerplants produce alternating current. The big difference between the two is that direct current is a flow of energy while alternating current can turn on and off and it reverses the direction of the electrons.

The motors of household appliances especially cooling systems works base on the concept of electromagnetic induction which is a branch of electromagnetism. According to the Lorenz Force Principle, electric motor moves through the magnetic field produced by the electric current (Applications of Electromagnetism, 2015). An specific example is how the motor of an electric fan works. As current flows though the moto, the electromagnet rotates which causes the shaft to rotate as well. The rotating shaft is what makes the blades of the fan turn (Electromagnetic Devices, 2019).

Electricity is a form of energy that results to the flow of charged particles. It is both a basic part of nature and considered one of the most widely used forms of energy. According to the Energy Information Administration (2009), the electricity that we use is a secondary energy source, because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy, and wind energy, into electrical power. Moreover, electricity is also referred to as an energy carrier, which means that it can be converted to other forms of energy such as mechanical energy or heat. On the other hand, primary energy sources are renewable or nonrenewable energy, but the electricity we use is neither renewable nor nonrenewable.
