Essay Example on Force: The Key to Electric Power Generation

Introduction

Force is a push or a pull on objects that result from the interaction with other objects (Glazebrook, 2016). In some situations, the interaction causes physical changes. In electricity generation, force is very crucial in aiding the turning of turbines. There are several effects produced by force on objects, they include causing objects to change direction, it stops moving objects, and it causes a change in the shape of the object. Electricity and magnetism are highly associated, flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. The most common type of force in electricity is the electromagnetic force(Kelly, 2014). This force is an interaction between electric force and magnetic force. In magnetism, the primary type of force is a magnetic force. Without electricity, the world would be dark, and without magnets, power could not have been produced. Therefore, electricity and magnetism are essential to the operation of almost every gadget, appliance, machines and even vehicles.

Importance of Electromagnetic Forces

The electromagnetic force is a fundamental manifestation of electricity and magnetic forces. However, in practice they have different behaviors, magnetism helps in the generation of electricity. When magnets spin around a wire, they result in a flow of charged particles through the cables. Charged particles are produced when atoms gain or lose electrons. Charged electrons are called ions(Petersen, 2015). When an atom loses electrons, it becomes negatively charged. Negatively charged electrons repel each other and as a result, some of them "leap" to positively charged particles to balance out. When electrons move from one atom to the other, in a wire, they generate an electric current. The force involved in this process is called the ionic force that is caused by the repulsion of the ions.

The flow of electricity in the wire is enhanced by the movement of electrons from one atom to the other. However, different materials have different affinities to gain or lose electrons. This is the reason why some elements are good conductors of electricity while others are not. For instance, the materials used to insulate electric wire is a poor conductor of electricity; this means that it cannot be easily ionized (Glazebrook, 2016). Rubber and plastics are commonly used insulators. Therefore the electric current created from the magnetic force is prevented from flowing out of the wire by rubber insulators that prevent electric shocks when one comes into contact with a charged wire.

Forces are very crucial in the daily life of human beings. They are used to provide energy in a variety of ways. However, three devices that force directly makes them function are such as a wheelbarrow, hammer, or a bicycle. In a wheelbarrow, force is used to push the load from one place to another with ease (Glazebrook, 2016). A hammer is used to drive in or out nails from a surface. When the hammer interacts with the nail, it forces it inside the surface, and the same force is used to pull the nail out of the same surface. When riding a bicycle, force is applied on the pedal causing the rotation of the wheel which causes a change in motion. Therefore, the life of a human is enhanced by the use of force. Force is the core of human functioning.

Conclusion

Electricity is generated by the action of spinning magnets that creates a magnetic field in a wire that causes an electric current to flow. Therefore magnetic forces are essential to life as electricity forces. Movement of electrical current through the wire is caused by the action of charged electrons (ions) from one atom to the other. The action results from ionic repulsion felt by ions in the electric field. Electricity and magnetic forces work associatively to generate electricity that is used by various gadgets, and appliance.
