tesla
Definition
- Noun:
- A unit of magnetic flux density: The tesla is the standard SI (International System of Units) unit for measuring the strength of a magnetic field. It is defined as one weber of magnetic flux per square meter.
- Nikola Tesla: A Serbian-American inventor, electrical engineer, and futurist. He is renowned for his contributions to the design of the modern alternating current (AC) electricity supply system.
Examples of Usage
- As a unit of measurement:
- A typical refrigerator magnet has a strength of about 0.001 tesla.
- The MRI machine uses a powerful magnet with a field strength of 1.5 or 3 tesla.
- As a proper noun (person):
- Tesla's work on alternating current was crucial for the development of modern electrical power systems.
- The electric car company is named after the inventor Nikola Tesla.
Advanced Usage
- The unit is often abbreviated as T (e.g., 2 T, 10 mT for millitesla).
- In scientific contexts, it is used to quantify extremely weak fields (like the Earth's magnetic field, ~50 microteslas) and extremely strong fields (like those in experimental physics labs, which can be many teslas).
Variants and Related Words
- Tesla coil (noun): A type of resonant transformer circuit invented by Nikola Tesla, used to produce high-voltage, low-current, high-frequency alternating-current electricity, often seen creating dramatic electrical arcs.
- Microtesla (µT) (noun): One-millionth of a tesla.
- Millitesla (mT) (noun): One-thousandth of a tesla.
- Kilotesla (kT) (noun): One thousand teslas (used for exceptionally strong fields).
Synonyms
- For the unit: There is no direct synonym for the SI unit "tesla." In the older CGS system, the equivalent unit is the gauss (1 tesla = 10,000 gauss).
- For the person: Inventor, engineer, visionary.
Related Phrases
- Tesla turbine: A bladeless centripetal flow turbine patented by Nikola Tesla.
- Tesla valve: A fixed-geometry passive check valve invented by Tesla, which allows fluid to flow preferentially in one direction without moving parts.
Noun
-
United States electrical engineer and inventor (born in Croatia but of Serbian descent) who discovered the principles of alternating currents and developed the first alternating-current induction motor and the Tesla coil and several forms of oscillators (1856-1943)
-
a unit of magnetic flux density equal to one weber per square meter
