31. In contrast to QED, the gluon field strength tensor is not gauge invariant by itself. 32. Magnetic field strength drops off rapidly with increasing distance. 33. The electric field strength is commonly measured using a crystal detector or Schottky barrier diode. 34. This led twentieth century physicists to classify RR field strengths using cohomology with integral coefficients. 35. The surface magnetic field strength is 1, 375 Gauss. 36. See Orders of magnitude ( magnetic field ) for examples of other magnetic field strengths . 37. Where \ mathbf E is the electric field strength , and V is the electric potential. 38. In fact, this is the origin of the quadratic term in the field strength tensor. 39. Sweeping under vacuum at higher temperatures and higher field strengths yields yet more radiation-hard crystals. 40. Does the magnetic field strength have to change?
