Figure a shows an element of length d s = 1.00m in a very long straight wire
Question:
Figure a shows an element of length d s = 1.00μm in a very long straight wire carrying current. The current in that element sets up a differential magnetic field dB at points in the surrounding space. Figure b gives the magnitude dB of the field for points 2.5 cm from the element, as a function of angle θ between the wire and a straight line to the point. The vertical scale is set by dB s = 60.0μT. What is the magnitude of the magnetic field set up by the entire wire at perpendicular distance 2.5 cm from the wire?
Wire ds (a) dB, A/2 e (rad) (b)

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.
