The tesla (symbol T) is the SI derived unit of magnetic field B (which is also known as "magnetic flux density" and "magnetic induction"). One tesla is equal to one weber per square meter, and it was defined in 1960 in honour of the Serbian inventor, physicist, and electrical engineer Nikola Tesla. One billionth of a tesla is a nanotesla (nT), equivalent to 0.01 mG (milligauss), and it is in nanoteslas that common metric home measurements are made to determine local magnetic field levels. The strongest fields encountered from permanent magnets are from Halbach spheres which can be over 5. A particle carrying a charge of 1 coulomb and passing through a magnetic field of 1 tesla at a speed of 1 meter per second experiences a force of 1 newton, according to the Lorentz force law. As an SI derived unit, the tesla can also be expressed as \mathrm{1\, T = 1\,\frac{V\cdot s}{m^2} = 1\,\frac{N}{A\cdot m} = 1\,\frac{Wb}{m^2} = 1\,\frac{kg}{C\cdot s} = 1\,\frac{kg}{A\cdot s^2}} (in SI base units). Units used: A = ampere C = coulomb kg = kilogram m = meter N = newton s = second T = tesla V = volt Wb = weber Conversions 1 tesla is equivalent to: 10,000 (or 104) G (gauss), used in the CGS system. Thus, 10 G = 1 mT (millitesla), and 1 G = 10−4 T. 1,000,000,000 (or 109) γ (gammas), used in geophysics. Thus, 1 γ = 1 nT (nanotesla) For those concerned with low-frequency electromagnetic radiation in the home, the following conversions are needed most: 1000 nT (nanotesla) = 1 µT (microtesla) = 10 mG (milligauss) 1,000,000 µT = 1 T For the relation to the units of the magnetizing field (amperes per meter or oersteds) see the article on permeability. * 31 µT (3.1×10−5 T) - strength of Earth's magnetic field at 0° latitude (on the equator) * 5 mT - the strength of a typical refrigerator magnet * 1 T to 2.4 T - coil gap of a typical loudspeaker magnet * 1.5 T to 3 T - strength of medical magnetic resonance imaging systems in practice, experimentally up to 8 T 「特斯拉」重定向至此。關於特斯拉的其他意思,詳見「特斯拉 (消歧義)」。 本文介紹的是磁感应强度。關於美籍塞尔维亚电子工程师,詳見「尼古拉·特斯拉」。 特斯拉(tesla),符号表示为T,是磁通量密度或磁感应强度的国际单位制导出单位。在1960年巴黎召开的国际计量大会上,此单位被命名以纪念在电磁学领域做出重要贡献的美籍塞尔维亚发明家、电子工程师尼古拉·特斯拉。特斯拉用以衡量特定区域通过的总磁通量,因而,减小面积便会增加磁通量密度。 1 T = 1 V · s · m -2 = 1 kg · s -2 · A -1 = 1 N · A -1 m -1 = 1 Wb · m -2 例子 在外太空,磁通量密度在0.1到10纳特斯拉之间(10-10 T 到 10-8 T) * 在地球磁场,50°纬度地区磁密是20微特斯拉(2×10-5 T),在赤道0°纬度上,磁密是 31 µT (3.1×10-5 T) * 一超大型馬蹄形磁鐵的磁場:1毫特斯拉(0.001 T) * 一大型30磅的擴音器磁鐵,線圈間磁場有1 T * 醫院用的磁振造影主磁鐵常為1.5 T及3 T最高達4 T;(對人)研究用途的最高達7 T * 太陽黑子的磁場強度為 10 T * 化學研究上的核磁共振主磁鐵常為11.74 T;以超導磁鐵達成者,最高磁場達25 T * 人類於實驗室(佛羅里達州立大學的美國國家高磁場實驗室,位在美國佛羅里達州塔拉哈西)中產生最強的持續磁場為 45 T * 實驗室中產生的瞬間最強磁場的紀錄為 (Koichi Kindo at 大阪大學), 80 T * 最强的人造磁场(爆炸产生于俄国Sarov)是2800 T * 在中子星上的磁場等級為1至100兆(106)特斯拉(106 T至108 T) * 在磁星上的磁場等級為0.1至100吉(109)特斯拉(108 T至1011 T) * 理論預估中子星最大磁場,同時也是任何可能的最大自然界磁場為 1013 T 地球物理學(Geophysics)使用非國際單位制的單位,稱作「伽瑪」(gamma, γ),1 γ = 10-9 T = 1 nT。 CGS制中的磁場單位為高斯 = 10-4 T。
