Why do EM waves not require a medium?
Both electrostatic fields and magnetic fields can influence objects in a vacuum, so EM waves (the combination of varying electromagnetic and electrostatic fields) have influence through a vacuum, that is, in the absence of a physical medium.
What fields are present near electricity?
Electromagnetic and electrostatic fields are present. The strength of each field is dependent upon the components in the electrical circuit.
What is the difference between positive and negative electric fields?
Positive electric fields attract negative charges while negative electric fields attract positive charges.
What is dielectric material?
A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields
What are all charged objects surrounded by?
A charged object is surrounded by a standing electrostatic field.
What is Electrostatic fields in matter?
what is the difference between matter and electrostatics

What is the difference between evolution and sociology?
These are two entirely separate fields of enquiry.
What has the author Gregory A Kallio written?
Gregory A. Kallio has written: 'Interaction of electrostatic and fluid dynamic fields in wire-plate precipitators' -- subject(s): Electrostatic precipitation
What is the difference between positive and negative electric fields?
Positive electric fields attract negative charges while negative electric fields attract positive charges.
What is the difference between the uses of tractor and excavator?
tractors are for plowing fields. excavators are for digging.
What is the difference between research in the lab and fields?
In the lab you have more control over variables
What is dielectric material?
A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields
What is the difference between microeconmics and macroeconomics?
Microeconomics and macroeconomics are two major and are general fields of economics.
What three forces can act from a distance?
There are only two forces that act at a distance:gravity, andelectromagnetism.Magnetic fields are sometimes referred to as a third force, however magnetism and electrostatic forces are both examples the electromagnetic force.
What has the author Terence M O'Donnell written?
Terence M. O'Donnell has written: 'Solution techniques for the finite element analysis of nonlinear magnetostatic problems in 2 and 3 dimensions' -- subject(s): Engineering mathematics, Finite element method, Electromagnetic fields
