When electric charge flows from one place to another, it induces a magnetic field.
The direction of the magnetic field is found by the right hand rule. To use the right hand rule, put your right hand into a fist with your thumb pointed up. When your point your thumb in the direction of the current, and the direction your fingers gives you the direction of the magnetic field.

Is voltage an excess accumulation of electric charge?
Sort of ... 1) Voltage is ALWAYS a comparison, thus it requires two reference points. 2) Its the density of the charge that counts, thus a gigantic charge over a very large area would result in a low voltage.
How an object can be measure by its change in position from one area to another?
motion
What is Implied Degree of Generalization?
It is the point at which it is implied that the area is within another.
Force can be calculated as pressure x area Which of the following will produce the most force?
10 p over 10 m2
A complete path for electricity to flow?
currents can be thought of simply by flowing through a wire, though not always the case. It is convenient to think of current density which is the amount of current flowing through a cross sectional area, like water through the opening of a pipe, since electric current flows through many 3-dimensional objects.
What is the movement of static electricity called?
The movement of static electricity is called discharge. This occurs when an excess of electric charge accumulates in one area and then seeks to neutralize by moving to another area with a lower charge.
What is the area that surrounds an electric charged called?
The area that surrounds an electric charge is called an electric field. It exerts a force on other charged objects in the vicinity, either attracting or repelling them depending on their charge.
What is area around an electric charge which is strongest closest to the charged particle?
electric field
How does the presence of an electric charge affect the surrounding electric field in the context of physics?
The presence of an electric charge creates an electric field around it. This electric field exerts a force on other charged objects in the surrounding area. The strength and direction of the electric field depend on the magnitude and sign of the charge.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
What is charge density and how does it relate to the distribution of electric charge within a given volume?
Charge density refers to the amount of electric charge per unit volume. It is a measure of how concentrated the electric charge is within a given space. The charge density is directly related to the distribution of electric charge within that volume, as a higher charge density indicates a greater concentration of charge in a specific area, while a lower charge density indicates a more spread out distribution of charge.
What is the surface charge density on the disks?
The surface charge density on the disks is the amount of electric charge per unit area on the surface of the disks.
Why do electric fans produce air?
Electric fans produce air by using an electric motor to rotate blades, creating airflow. The movement of the blades pushes surrounding air, creating a breeze that helps to cool the surrounding area.
What answer best describes the flow of electrical charge?
The flow of electrical charge is the movement of electrons through a conductor. Electrons move from an area of high potential (voltage) to an area of low potential, creating an electric current. This flow is driven by the presence of an electric field.
What is the relationship between surface current density and the flow of electric charge in a conducting material?
Surface current density refers to the flow of electric charge per unit area on the surface of a conducting material. It is directly related to the flow of electric charge within the material, as the surface current density is a result of the movement of charge carriers within the material. In other words, the higher the surface current density, the greater the flow of electric charge within the conducting material.
What is the Difference between line charge density and surface charge density?
The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.
What is the opposition to flow of electric charge?
The opposition to the flow of electric charge is called resistance. It is measured in ohms and can be influenced by factors like the material of the conductor, its length, cross-sectional area, and temperature.
