As the core motion changes over time, due to complex geodynamic conditions within the core and at the boundary with the solid mantle up above, the magnetic field fluctuates in space and time too.the magnetic field around a line is proportional to the current. This means that the magnetic field level increases as the current in the line increases. Very high voltage lines 345 kV can carry high current and as a result produce relatively high magnetic fields.Dec 20, 2019 NIST is developing ultra-miniaturized, low-power magnetic and electric field sensors that produce dependable readings without ever needing to be calibrated by other devices. They provide measurements traceable to the International System of Units SI, ensuring consistent results anytime and anywhere in the world.2. Magnetic Field Electric field 1 A distribution of electric charge at rest creates an electric field E in the surrounding space. 2 The electric field exerts a force F E q E on any other charges in presence of that field. Magnetic field 1 A moving charge or current creates a magnetic field in the surrounding space in addition to E.The electric field of a charge distribution can be found using the principle of superposition. Field lines can be used to visualize the electric field. There are no magnetic charges. Moving electric charges produce magnetic fields. To produce a magnetic field B, a current density j is needed, i.e. j v - v- cannot be zero.
