41. The surface of the Earth has a standard gravitational field strength of 9.80665 N / kg. 42. Very little energy flows in the conductors themselves, since the electric field strength is nearly zero. 43. In quantum field theory it is used as the template for the gauge field strength tensor. 44. The magnetic moment induced by the applied field is linear in the field strength and rather weak. 45. To generate a sufficient field strength , the audio signal on the grids must be of high voltage. 46. This allows rare earth magnets to be smaller than other magnets which produce the same field strength . 47. At zero field strength , the magnetization is offset from the origin by an amount called the remanence. 48. The connection " A " on the fiber bundle is related to the electromagnetic field strength as 49. The electric field strength within the thundercloud is not typically large enough to initiate this process by itself. 50. The power density per surface unit is proportional to the product of the electric and magnetic field strengths .
