Question:
In Figure two infinitely long wires carry equal currents i. Each follows a 90? arc on the circumference of the same circle of radius R. Show that the magnetic field B at the center of the circle is the same as the field B a distance R below an infinite straight wire carrying a current i to the left.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
