Electricity and Magnetism are two of the most mysterious forces of nature which are interrelated and give rise to the effect known as the magnetic effect of electric current. This blog post aims to shine a light on this complex process, outlining its foundations, possible uses, and role in our lives as contemporary humans.

Understanding the Phenomenon:

Fundamentally, the magnetic effect of an electric current is caused by the displacement of electric charges, mainly the electrons in a conductor. Whenever current flows through a conductor, it creates a magnetic field around the conductor. This magnetic field can be visualized as a series of concentric circles with the radius perpendicular to the current flow. The farther away you are from the conductor, the weaker the strength of the field.

To express mathematically the magnetic field produced by a current-carrying conductor, we are going to use Ampere’s law. This law is called the Biot-Savart’s law and formulated by the famous physicist Ampère. It says that the magnetic field intensity is proportional to the current strength and the number of turns of a coil.

Applications in Everyday Life:

Magnetism of an electric flow is something we are surrounded by every single day; it powers and supports the devices and technologies that we underestimate. undefined

Electromagnets: These are the coils of wires wound around an iron core, which can create strong magnetic fields when current flows through them. Electromagnets have wide applications, such as magnetic cranes, MRI machines and speakers.

Electric Motors: The electric motors use the interaction of magnetic fields and electric currents for rotational movement. They can be found in a number of devices for instance fans, fridges and washing machines and machines for the industrial sector and vehicles.

Magnetic Compasses: The magnetic needle of the compass aligning with the Earth’s magnetic field is a demonstration of magnetic effects of electric current. Magnetic compasses have played a vital role in navigation since time immemorial, being the guide of travelers and explorers over the land and over the sea.

Magnetic Levitation (Maglev) Trains: Maglev trains are levitated and propelled by high power electromagnets through a guideway which therefore eliminates the need for wheels or tracks.This technology offers high-speed transportation with minimal friction, promising a greener and more efficient future for mass transit.

Induction Cooking: Induction cooktops use magnetic fields to generate electric currents in the cookware that is ferromagnetic, giving off heat for cooking. This leads to cooking processes with high precision and instantaneous temperature control, which in turn revolutionizes the culinary experience.

Conclusion:

The magnetic effect of an electric current will turn out to be a truly profound and multidimensional phenomenon, which is hard to imagine our world without. The applications of this phenomenon are as varied as they are invaluable. They range from electromagnets and electric motors as well as magnetic compasses and induction cooktops. We not only comprehend but also exploit the laws of magnetic fields to surpass the limits of technological advancement and stay ahead in developing futuristic world.
