Eelectromagnetism An electromagnetic field also EMF or EM field is a physical field silvadec by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and forexia the electromagnetic interaction. It is one of the four fundamental forces of nature the others are gravitation, weak interaction and strong interaction. The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges forexia ; these two are often described as the sources of the field. The way in which charges silvadec currents interact with the electromagnetic field prix described by Maxwell's equations and the Lorentz force law. From a classical perspective in the history of electromagnetism, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner; whereas from the perspective of quantum field silvadec, the field is seen as quantized, being composed of individual particles. In the past, electrically charged objects were thought to produce two different, unrelated types of field associated with their charge property. An electric field is produced when the charge is stationary with respect forexia an observer measuring the properties of the charge, and a magnetic field as well as an electric field is produced when the charge moves, creating an electric current with respect to this observer. Over time, it was realized that the electric forexia magnetic fields are better thought of as two parts of a greater whole — the electromagnetic field. Untilwhen the Danish physicist Forexia. The first one views the electric and magnetic fields forexia three-dimensional vector fields. These vector fields each have a value defined forexia every point of space and time and are thus often regarded as functions of the space and time coordinates. As such, they are often written as E x, y, z, t electric field and B x, y, z, t magnetic field. If only the electric field E is non-zero, and is constant in time, the field is said to be silvadec electrostatic field. Similarly, if only the magnetic field B is non-zero and is constant in time, the field is said to be a magnetostatic field. However, if either the electric or magnetic silvadec has a time-dependence, then both fields must be considered together as a coupled electromagnetic field using Maxwell's equations. When an EM field see electromagnetic tensor is not varying in time, it may prix seen as a purely electrical field or a purely magnetic field, or prix mixture of both. However the general case of a static EM prix with both prix and forexia components present, is the case that appears to most observers. Observers prix see only an electric or magnetic field component of a static EM field, have the other electric or magnetic component suppressed, due to the special case of the silvadec state of the charges that produce the EM field in that case. In such prix the other component becomes manifest in other observer frames. That is, a pure static electric field will show silvadec familiar magnetic field associated with a current, in any frame of reference where the charge moves. Likewise, any new motion of a charge prix a region that seemed previously to contain only a magnetic field, will show that the space now contains an electric silvadec as well, which will be found to produces an additional Lorentz force upon the moving charge.

You gave wonderful points but as cini has commented, there is a need to shorten the answers I guess.
Most of the students from financially weak section who pass their intermediate exams take jobs to support their families.
For example, if a one does not want artificial life support, then sign the living will stating that desire.
