A strip of copper 150m thick and 4.5 mm wide is placed in a uniform magnetic field
Question:
A strip of copper 150μm thick and 4.5 mm wide is placed in a uniform magnetic field B of magnitude 0.65 T, with E perpendicular to the strip. A current i = 23 A is then sent through the strip such that a Hall potential difference V appears across the width of the strip. Calculate V. (The number of charge carries per unit volume for copper is 8.47 x 1028 electrons/m3)

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.
