Hello, I know the electromagnetic field propagates in a 3D space so if I am horizontally aligned with the field I will receive its variation but what if I'm vertically aligned ?
thanks
thanks
scientifico said:yes an antenna put about horizontally compared to the charge will receive the em field variations bat what if the antenna is above it ?
scientifico said:By above it I mean a situation like this. will antenna 1 receive nothing ?
scientifico said:so does the charge vibrate in all directions not just up and down ?
when an electromagnetic wave falls on a charged particle,then the electric field will accelerate it and it gets a velocity in that direction .After it,magnetic field will act because it can not not act if particle does not have a velocity.The magnetic field exerts the force on the charge particle in the direction of propagation of wave,as is easily seen because of lorentz force law.So it is only the E field which will cause the oscillatory motion in up and down direction and that is what is meant by polarization of EM wave.scientifico said:so does the charge vibrate in all directions not just up and down ?
An electromagnetic field is a physical field created by the movement of electrically charged particles. It is composed of electric and magnetic components and can exist in a variety of forms, including a vertical orientation.
The orientation of an electromagnetic field can affect its strength and direction. In a vertical orientation, the electric and magnetic components are perpendicular to each other and the direction of propagation is also perpendicular, resulting in a unique pattern of energy flow.
The sources of electromagnetic fields in a vertical orientation can vary, but some common sources include power lines, radio and television antennas, and lightning strikes. These fields can also be generated by man-made devices, such as MRI machines.
There is ongoing research on the potential health effects of exposure to electromagnetic fields, including those in a vertical orientation. Some studies suggest a link between prolonged exposure to high levels of electromagnetic fields and increased risk of certain health issues, but more research is needed to fully understand the effects.
Electromagnetic fields can be measured using specialized instruments, such as gaussmeters and spectrum analyzers. These devices can detect the strength and frequency of the field and provide data for monitoring purposes. Additionally, regulations and guidelines are in place to ensure safe levels of exposure to electromagnetic fields.
