Question:
A long wire is known to have a radius greater than 4.0 mm and to carry a current that is uniformly distributed over its cross section. The magnitude of the magnetic field due to that current is 0.28mT at a point 4.0 mm from the axis of the wire, and 0.20mT at a point 10 mm from the axis of the wire. What is the radius of the wire?

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.
