ExahenryEH
Source UnitThe exahenry (symbol: EH) is a derived unit of inductance in the International System of Units (SI), representing a value of 10^18 henries. Inductance quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. It is a fundamental property in electrical circuits, particularly in components like inductors and transformers. The henry, the base unit for inductance, honors Joseph Henry, a pioneer in electromagnetism, and serves as the cornerstone for defining larger units such as the exahenry. The exahenry is predominantly used in theoretical physics and advanced electrical engineering, where extremely large inductances are discussed, particularly in contexts involving high-energy systems.
Current Use
The exahenry is primarily used in theoretical and specialized practical applications within the fields of electrical engineering, physics, and technology. While not frequently encountered in everyday applications, the exahenry finds relevance in high-energy systems such as particle accelerators, advanced power generation systems, and large-scale electromagnetic devices. Countries with significant advancements in electrical engineering and research, such as the United States, Germany, and Japan, utilize the exahenry in academic and industrial settings. In these environments, the exahenry serves as a conceptual tool for discussing the inductive properties of complex electrical networks and systems, particularly where conventional units are inadequate.
Fun Fact
The exahenry is one of the largest units of inductance in the SI system, making it rare in practical applications.
HenryH
Target UnitThe henry (H) is the SI unit of inductance, which quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. Specifically, one henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. This definition underscores the relationship between current, voltage, and inductance, which is critical in understanding electromagnetic phenomena. The henry serves as a fundamental unit in electrical engineering and physics, particularly in the study of circuits, transformers, and inductors. In practical terms, inductance is crucial for the functioning of various electrical and electronic devices, influencing their performance and efficiency.
Current Use
The henry is widely used in various industries including electronics, electrical engineering, and telecommunications. In electrical engineering, inductorsācomponents that store energy in magnetic fieldsāare characterized in henries. Devices such as transformers, motors, and generators utilize inductance to function efficiently, making the henry a vital metric in their design and operation.

Definition
The exahenry (symbol: EH) is a derived unit of inductance in the International System of Units (SI), representing a value of 10^18 henries. Inductance quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. It is a fundamental property in electrical circuits, particularly in components like inductors and transformers. The henry, the base unit for inductance, honors Joseph Henry, a pioneer in electromagnetism, and serves as the cornerstone for defining larger units such as the exahenry. The exahenry is predominantly used in theoretical physics and advanced electrical engineering, where extremely large inductances are discussed, particularly in contexts involving high-energy systems.
History & Origin
The concept of inductance was first introduced in the early 19th century, primarily through the work of physicists such as Michael Faraday and Joseph Henry. Their experiments with electromagnetic induction laid the foundation for understanding how electric currents create magnetic fields. The henry was established as the base unit of inductance in 1861, named after Henry, who independently discovered self-induction. The need for larger units arose as technologies advanced and applications in electrical engineering expanded, leading to the formal acceptance of the exahenry in 1959 as part of a systematic approach to scaling units within the metric system.
Etymology: The term 'exahenry' derives from the prefix 'exa-', which means 10^18, combined with 'henry', named after the American scientist Joseph Henry.
