Which of the following statements are true concerning the creation of magnetic fields? check all that apply.

a single stationary electric charge creates a magnetic field at all points in the surrounding region. a distribution of electric charges at rest creates a magnetic field at all points in the surrounding region. a moving electric charge creates a magnetic field at all points in the surrounding region. a permanent magnet creates a magnetic field at all points in the surrounding region. an electric current in a conductor creates a magnetic field at all points in the surrounding region.

Answer;A moving electric charge creates a magnetic field at all points in the surrounding region.An electric current in a conductor creates a magnetic field at all points in the surrounding region.A permanent magnet creates a magnetic field at all points in the surrounding region.Explanation;A magnetic field describes a volume of space where there is a change in energy.Magnetic field is produced whenever an electrical charge is in motion. Therefore, the motion of an electric charge produces a magnetic field. Magnetic field depend on the charge, velocity, and acceleration of the particles. Magnetic field and electric field are related such that an electrical charge in motion causes a magnetic field, and a magnetic field in motion causes an electric field.
