What surrounds electric charges and exerts force on other charges?
An electric field surrounds the charge and exerts force on other charges.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
What is fringing electric field?
Fringing effect is the magnetic characteristic caused by the shape around directly opposing the magnetic surfaces.
What is the principle of electrostatic shielding?
The method of protecting a region from the effect of electric field is called electrostatic shielding. The electric field inside the cavity of a conductor is zero. Therefore, any instrument or an appliance can be placed in the cavity of a conductor so that it may not be affected by the electric field.
What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this

Will changing the electric field will have no effect on the magnetic fields of a body?
yes, it will, from my book.

What is magnetic effect of electric current?
A magnetic field is induced around any conductor carrying an electric current.As explained in the Oersted Theory.
What is tunnelling effect in STM?
The tunneling effect is the principle by which STM works. The tunneling effect is the jump of electrons from a metal or semiconductor produced by applying a strong electric field.
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
What is an edge effect?
My guess is you're referring to the edge effect on electric fields. In many textbooks, and many problems dealing with electric fields you will see assumptions used to minimize the effect an edge has on the electric field you're attempting to analyze, which is done to simplify the problem. One common example is determining the electric field strength at a point a given distance from a conductor carrying X amount of current. It's often assumed that this is an infinitely long conductor. This removes the need to analyze the electric field due to the corner of the conductor, where the shape, sharpness of the corner, size, type of conductor, and amount of current can impact the actual effect that corner has on the electric field strength at a given distance from the conductor. Usually the impact of the corner is minor, so it can be ignored by assuming an infinite conductor. Other examples: -calculating the electric field X distance from a charged plate (assume the plate is infinite)
