free electron hav random motion in all posible
Electric current flows in metals due to the movement of free electrons. When a voltage is applied across a metal conductor, the electric field created causes the free electrons to move in the direction of the field, creating a flow of charge which we refer to as electric current.
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
electromagnetic induction
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.

The Magnetic field itself can do no work and is a byproduct of the electric current. The energy is stored in the current or provided by whatever drives the current.
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
Electron movement is primarily caused by an electric field. When a voltage is applied across a conductor, such as a wire, the electric field pushes the free electrons in the conductor to move in a particular direction, creating an electric current.
for apex its: a quantum field, a gravitational field
yes. electric current low always generates a magnetic field.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
This device is called a generator. When a magnetic field is moved across a wire, it induces a flow of electrons in the wire, creating an electric current. Generators are commonly used to convert mechanical energy into electrical energy in power plants and electric generators.
