Hans Christian Ørsted discovered the link between electricity and magnetism
Hans Christian Ørsted was a Danish chemist and physicist born in Rudkøbing, Denmark, on 14 August 1777. Ørsted's father was a pharmacist, and Ørsted received most of his early education through self-study at home. At the age of 13, he began working for his father and developed an interest in science. In 1793, Ørsted travelled to Copenhagen to take the entrance exams for the University of Copenhagen, where he excelled academically and studied physics, philosophy, and pharmacy. He earned a PhD in philosophy in 1799, writing his dissertation on Immanuel Kant's philosophy of nature.
In 1800, Ørsted was inspired by Alessandro Volta's invention of the voltaic pile to investigate the nature of electricity and conduct his first electrical experiments. He also met Johann Wilhelm Ritter, a physicist who believed in a connection between electricity and magnetism, which Ørsted subscribed to as a Kantian. In 1806, Ørsted became a professor at the University of Copenhagen, where he continued to study electric currents and acoustics.
On 21 April 1820, Ørsted made his most famous discovery. While setting up his apparatus during a lecture, he noticed that when he turned on an electric current by connecting a wire to both ends of a battery, a nearby compass needle deflected away from magnetic north. This surprising occurrence provided definite experimental evidence of the relationship between electricity and magnetism, as an electric current flowing through a wire could move a nearby magnet. This discovery, known as Oersted's law, set the stage for the development of our modern technology-based world. Ørsted published his results in a pamphlet in July 1820, which was circulated privately to physicists and scientific societies, and incited a tremendous outbreak of research in the field of electromagnetism.
For his discovery, Ørsted was awarded the 1820 Copley Medal by the British Royal Society, the greatest prize in science, and 3,000 gold francs by the French Academy. The centimetre-gram-second system (CGS) unit of magnetic induction was also named the "oersted" in honour of his contributions to electromagnetism.

Ørsted's work led to the development of modern technology
Hans Christian Ørsted was a Danish chemist and physicist who made significant contributions to the understanding of electricity and magnetism. Ørsted's most notable discovery was that electric currents create magnetic fields, now known as Ørsted's law. This phenomenon, later known as electromagnetism, marked the beginning of a new scientific era and laid the foundation for modern technology.
Ørsted's interest in science began at a young age while working with his father, a pharmacist in Rudkøbing, Denmark. He pursued his passion for science and earned a doctorate in philosophy in 1799, with a dissertation influenced by Immanuel Kant's philosophy of nature. Ørsted's early career included lecturing and working as a pharmacist. He received a travel scholarship and grant in 1801, which allowed him to explore Europe and connect with prominent scientists. During his travels, he met Johann Wilhelm Ritter, a physicist who believed in the connection between electricity and magnetism, an idea that intrigued Ørsted.
In 1806, Ørsted became a professor at the University of Copenhagen, where he continued his research on electric currents and acoustics. His groundbreaking discovery came in 1820 when he observed that a magnetic needle aligned itself perpendicularly to a current-carrying wire. This provided concrete evidence of the relationship between electricity and magnetism. Ørsted's discovery sparked widespread interest and inspired further exploration in the field of electromagnetism.
The recognition of Ørsted's work extended beyond his home country. In 1820, the British Royal Society awarded him the Copley Medal, the highest honour in science, for his discovery of electromagnetism. The French Academy also acknowledged his achievements by awarding him 3,000 gold francs. Ørsted's name continues to be commemorated in various forms, including the unit of magnetic field strength in the centimetre-gram-second system, named the "oersted" in his honour.
Ørsted's work not only advanced scientific understanding but also paved the way for technological advancements. His discovery of the link between electricity and magnetism set in motion the development of modern technology. This breakthrough inspired innovations that shape our daily lives, from electric motors and generators to the vast array of electronic devices we rely on today.

Ørsted was inspired by Alessandro Volta's invention of the voltaic pile
Hans Christian Ørsted was a Danish chemist and physicist who discovered the link between electricity and magnetism. Ørsted's discovery of electromagnetism paved the way for the development of modern technology. He also discovered the chemical compound piperine and was the first to isolate the element aluminium.
Ørsted's interest in science began when he was a young boy working for his father, a pharmacist in the town's pharmacy. He went on to receive a PhD in philosophy at the age of 22. Ørsted's PhD focused on Immanuel Kant's philosophy of nature, which helped shape his view of the world.
In 1800, Alessandro Volta announced his invention of the voltaic pile, the first electric battery. The voltaic pile was a simple and reliable source of electric current, which allowed scientists to study electricity more effectively. This inspired Ørsted to investigate the nature of electricity and conduct his first electrical experiments.
Volta's battery consisted of alternating discs of zinc and silver (or copper and pewter) separated by paper or cloth soaked in saltwater or sodium hydroxide. This design replaced earlier designs that used wine goblets filled with brine, making it a simpler and more compact tool for scientists. The voltaic pile quickly became a favourite at public and private demonstrations, and within a year of its invention, Ørsted had begun his travels across Europe, meeting with scientists such as Johann Wilhelm Ritter, who believed in a connection between electricity and magnetism.
