Question

How could you prove that electric current produces a magnetic field?

Answer 1

Hint: When the charged object is with a conducting path, the electrons begin to pass through the path from higher potential to lower potential area. The potential difference is created by a cell or battery. When the electrons move, an electric current is produced. Electric current is produced by moving electrons. The movement of the positive charge is known as the conventional current. The flow of electrons is termed an electron current.

Complete step by step answer:
A wire or a conductor carrying a current produces a magnetic field perpendicular to the direction of the flow of current. This is called the magnetic effect of current. The discovery of the scientist proved he is also the discoverer of the right-hand thumb rule. Direction of current by the right-hand thumb and the direction of the magnetic field by the other fingers of the same right hand. The strength of the magnetic field at appointing due to current-carrying wire depends on the current in the wire, the distance of the point from the wire., the orientation of the point from the wire, and the magnetic nature of the medium.

Note :
Current is called a rate at which charges flow past a point on a circuit. \[q\] is the quantity of charge passing through a cross-section of a wire in time t, the quantity of current \[I\] .
\[\;\;I = \dfrac{q}{t}\]
The standard SI unit for current is known as ampere. It has the symbol \[A\] . The current of one ampere means that there is one coulomb of charge passing through a cross-section of a wire every one second. An ammeter is used to measure the strength of the current in an electric circuit.
