Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic field. The ones in microphones are very small, but in the video after the break [Jay Bowles ...

The principle is that the electric field associated with an intense (that ... This observation emphatically shows that molecules with a permanent dipole moment do not necessarily provide a larger ...

Quantum field theory marries the ideas of other quantum ... apart from the opposite electric charge. The positron, the first antimatter particle, was duly discovered in cosmic rays a few years ...

Furthermore, an alternating electric field is employed to polarize the passive particles, creating dipole-dipole repulsive forces that help assemble the particles into a specific configuration.

Understand cable impedance: explore the differences between 50-ohm and 75-ohm standards in RF design for improved performance ...
