How are all of the above fields different from each other what makes them what they are?Any comments would be appreciated.
Your explanation is a little vague for me to understand,so correct me if I'm wrong but are electric and magnetic fields an electromagnetic wave with different frequencies?M Quack said:They are all aspects of the same thing. Colloquially speaking electric fields usually implies static electric fields that do not vary in time (or that vary only very slowly), same for magnetic fields. Colloquially speaking about electromagnetic waves implies that the fields vary with some frequency.
Of course electromagnetic waves are composed of electric and magnetic field components that are coupled...

I think you answered most of my question, i understand that electric fields and magnentic fields make up electromagnetic waves now. I always thought that electric and magnetic fields formed a sphear shape but i assume that they form a wave when they are together...nsaspook said:I'll point you to the old Navy answer. http://electriciantraining.tpub.com/14182/css/14182_47.htm

An electric field is a physical field that is created by electrically charged particles. It is a force field that can exert a force on other charged particles within its influence. A magnetic field, on the other hand, is a physical field that is created by moving electrically charged particles. It is a force field that can exert a force on other moving charged particles within its influence. Essentially, the main difference between an electric field and a magnetic field is the source of the field - one is created by stationary charged particles and the other is created by moving charged particles.
Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. These fields are perpendicular to each other and travel through space at the speed of light. They are produced when an electric charge is accelerated or when a changing magnetic field is present. Essentially, electromagnetic waves are the result of the interaction between electric and magnetic fields.
Electric and magnetic fields are present in many aspects of our daily lives. Some examples include the electric fields produced by household appliances, such as computers and televisions, and the magnetic fields produced by power lines and speakers. They can also be found in nature, such as the Earth's magnetic field and the electric fields produced by lightning.
Electric and magnetic fields are measured using different units. The strength of an electric field is measured in volts per meter (V/m), while the strength of a magnetic field is measured in teslas (T). Both fields can be measured using specialized instruments, such as voltmeters and magnetometers. The strength of an electromagnetic wave, on the other hand, is measured in watts per square meter (W/m^2).
Electric and magnetic fields have numerous practical applications in our modern world. Some examples include their use in technology, such as in electric motors and generators, as well as in medical imaging, such as magnetic resonance imaging (MRI). They are also used in telecommunications, such as in cell phones and satellite communications. Additionally, electric and magnetic fields are used in research and scientific experiments to study the behavior of charged particles and to create controlled reactions.
