Was studying in class the effects of the E and B fields far from the source and what they looked like, but we failed to discover what happens near the source...Is this because there is no difference or did we just not cover the material
An oscillating dipole refers to a system of two opposite charges that are separated by a distance and are undergoing periodic motion. This motion creates an oscillating electric field and a corresponding oscillating magnetic field.
An oscillating dipole is significant because it is a fundamental concept in electromagnetism and plays a role in various physical phenomena such as radiation, resonance, and energy transfer.
The E and B fields near the source of an oscillating dipole are perpendicular to each other and to the direction of propagation. The electric field is strongest along the direction of motion of the charges, while the magnetic field is strongest at right angles to the direction of motion.
The strength of the E and B fields near the source of an oscillating dipole is affected by the frequency and amplitude of the oscillation, as well as the distance from the source. The strength of the fields decreases with increasing distance from the source.
Yes, an oscillating dipole can produce electromagnetic waves. As the charges in the dipole oscillate, they create changing electric and magnetic fields that propagate through space as electromagnetic waves. This is the basis of radio communication and other wireless technologies.
