Question

The figure shows four arrangements of circular loops of radius r or 2r, centered on vertical axes (perpendicular to the loops) and carrying identical currents in the direction indicated, in which arrangement, the magnitude of the net magnetic field at the dot is the greatest :

Answer 1

Answer:

where is the diagram

please let me know

Answer 2

The magnitude of the net magnetic field at the dot is the greatest in d, a tie of b and c arrangement. ( Option b is the correct answer)

• A magnetic field is a vector field that surrounds a magnet, an electric current, or a shifting electric field and contains magnetic forces that may be observed.
• Electric charges in motion and the intrinsic magnetic moments of elementary particles connected to their fundamental quantum feature known as spin create a magnetic field.
• A part of the electromagnetic force, one of the four fundamental forces of nature, magnetic field and electric field are interconnected.
• So, in the above picture we explain the magnetic movment for all arrangements.
• And after analysing the picture we understand that the correct arrangment is, d, a tie of b and c

Hence, d, a tie of b and c arrangement the magnitude of the net magnetic field at the dot is the greatest
