Magnetic field due to a current through a circular loop
Magnetic field due to a current through a circular loop To illustrate the magnetic field due to a current through a circular wire, we should take a straight wire and bend it in the form of the circular wire and electric current is passed through them. As we know that magnetic field produced by the current carrying straight conductor depends on the inversely to the distance from it. Similarly , at every points of a current carrying circular loop of the conductor , the concentric circles represents the magnetic field around it becomes larger and larger as we move from the conductor. A circular wire is made up of large number of the straight wire or conductor. Every arcs of the circles appear like as a straight line. every point on the circular wire is carrying current. And it gives rise to the magnetic field appearing as straight lines at the center of the loop. By applying right hand thumb rules , it is easy to check the ev...
