The mass of an object. The size of an object. Any natural satellites orbiting the object. Mostly th mass though.
The strength of an electric field is most affected by the magnitude of the charges creating the field and the distance between them. Increasing the magnitudes of the charges or decreasing the distance between them will increase the strength of the electric field.
The strength of an electric field is most affected by the magnitude of the electric charges creating the field and the distance between the charges. The strength decreases with increasing distance between charges and increases with increasing magnitude of the charges.
distance between charged particles.
The electric field around a charged object is most intense near the surface of the object where the charge is located. As you move away from the charged object, the electric field strength decreases.
Direction and electric flux density. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines.

Yes. An electric field is represented by electric field lines. Electric field lines are a visual representation of the strength and direction of an electric field in a region of space. In the vicinity of any charge, there is an electric field and the strength of the electric field is proportional to the force that a test charge would experience if placed at the point. (That is a matter of definition of electric field.) Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. In the case of arrows, they are vector representations of the strength and direction of the electric field at the point in space where each arrow is drawn.

There is a small caveat. It is not only charge that can produce electric fields. An electric field can be produced by a changing magnetic field. This is technologically important (since electric motors work on this principle) and scientifically fascinating, requiring a somewhat more sophisticated aspect of electromagnetic theory, but ultimately the electric field or electric flux can be visualized with lines (or arrows) in a manner exactly as is done for stationary charges.
Depends on the electrical field, but the most common way to tell is the metallic smell of ionized oxygen or ozone, a tingly feel on the skin, and hair standing on end. But that's only for strong electric fields. For weak electric fields the use of a some sort of meter is required.

A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.

Yes, electric heating pads produce electromagnetic fields due to the flow of electricity through the heating elements. The strength of the electromagnetic field varies depending on the design and power of the heating pad. However, the electromagnetic fields from electric heating pads are generally considered to be low and not a significant health concern for most people.
