A scientist studies a diagram of a tesla coil in a laboratory.

Definition

1. 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.
