Question

Which of the following statements are true concerning the creation of magnetic fields? Check all that apply. Check all that apply. A permanent magnet 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 distribution of electric charges at rest 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 single stationary electric charge creates a magnetic field at all points in the surrounding region.

Answer 1

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 can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. it is important to also note that charged particles create magnetic fields only when they are moving.
• The strength of the magnetic field generated or created is proportional to the amount of current flowing through the wire. Thus, increasing the current increases the strength of the magnetic field.
