The magnitude of the magnetic field at the location of the charge due to the current-carrying wire is given as B = μI/2πr.
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 magnitude of the magnetic field at the location of the charge due to the current-carrying wire is calculated as follows;
B = μI/2πr
where;
Thus, the magnitude of the magnetic field at the location of the charge due to the current-carrying wire is given as B = μI/2πr.
