1. a unit of magnetic flux density equal to one billionth of a tesla
Usage: scientific; physics

Examples

• The Earth’s magnetic field strength is approximately 50,000 nanoteslas.
• Scientists measured magnetic anomalies in increments of nanoteslas.
• The magnetometer detected variations as small as 10 nanoteslas.
• Brain activity produces magnetic fields measurable in nanoteslas.
• The research required precision instruments capable of detecting single nanoteslas.
• Magnetic field maps show values ranging from 25,000 to 65,000 nanoteslas globally.
