How is current related to magnetic field
When an EM field (see electromagnetic tensor) is not varying in time, it may be seen as a purely electrical field or a purely magnetic field, or a mixture of both. However the general case of a static EM field with both electric and magnetic components present, is the case that appears to most observers. Observers who see only an electric or magnetic field component of a static EM field, have the other (electric or magnetic) component suppressed, due to the special case of the imm… Web5 nov. 2024 · The apparatus used by Faraday to demonstrate that magnetic fields can …

What are the current standards? European power frequency. Mobile phone base station frequency. Microwave oven frequency. Frequency. Web28 mrt. 2015 · A winding (conductor) carrying direct current (DC) produces a magnetic field akin to a permanent magnet. The current carried by this conductor is unidirectional and steady i.e. it does not change direction or vary in magnitude with respect to time. Hence, the effect is that of a permanent magnet which simply attracts objects near the coil.
WebA magnetic field is a vector field that describes the magnetic influence on moving … WebThe magnetic field at a point due to a long wire is B = μ i 2 π d So the field is inversely proportional to the distance from the wire. So the field decreases due to the distance increases that is P moves further away or current decrease.
