Increasing the electric field magnitude along a wire will increase the current density. This is because a higher electric field will cause more electrons to move through the wire, resulting in a higher flow of electric current.
Current density is a vector quantity because it has both magnitude and direction. It represents the flow of electric charge per unit area in a specific direction, as opposed to current which is the total amount of charge flowing through a conductor. The direction of current density indicates the direction in which the charges are moving.
Current density is the amount of electric current flowing through a given area. It is calculated by dividing the current passing through a conductor by the cross-sectional area of the conductor. The formula for current density is J I/A, where J is the current density, I is the current, and A is the cross-sectional area.
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.
The divergence of current density in electromagnetism is significant because it helps us understand how electric charges are distributed in a given space. It is a key concept in Maxwell's equations, which describe how electric and magnetic fields interact. By studying the divergence of current density, we can analyze the flow of electric current and predict the behavior of electromagnetic fields in various situations.
Current density is denoted by J to indicate the amount of current flowing through a unit area in a given material. It is a vector quantity, representing the direction and magnitude of current flow in a specific direction. The letter J is commonly used as a symbol for current density in physics and engineering equations.

Current is not scalar. Current is a vector quantity. For simplicity, in electric circuits, current is scalar because the direction is assumed to be one way or another, rather than three dimensional.

We know specifically the definition of current density as current flow through a surface of unit area. Conduction current is the current through the conductors in the presence of electrostatic fields and displacement current is the current flow due to time varying electric fields

The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.
