Growth factors are organized into three categories. Some bacteria (e.g. E. coli) do not require any growth factors: they can synthesize all essential purines, pyrimidines, amino acids and vitamins, starting with their carbon source, as part of their own intermediary metabolism.
The inductor is a conductor, usually a coil of wire, that stores energy in a magnetic field in response to the current through it. When the current changes, the magnetic field does too, inducing a voltage between the ends of the conductor.The induced voltage is proportional to the time rate of change of the current.he electric potential at any point is defined as the energy required to bring a unit test charge from an infinite distance slowly to that point. It is usually measured in volts, and one volt is the potential for which one joule of work must be expended to bring a charge of one coulomb from infinity.
DEMAGNETIZING FORCE: A magnetized force applied in a direction that reduces the field in a magnetized material. FLUX: Another term for the magnetic field. GAUSS: The unit of magnetic induction or magnetic flux density used to measure magnetic field strength.AGNET: A material that has the property, either natural or induced, of attracting iron or steel. MAGNETIC FIELD: The space around a magnet in which the magnetic force can be detected. MAGNETIC FLUX: The total magnetic induction across or through a specified area.
