How is a magnetic field generated?
Understand the Problem
The question is asking how magnetic fields are generated. This involves understanding concepts related to electromagnetism, including the movement of electric charges and the principles behind magnetic fields.
Answer
Magnetic fields are generated by moving electric charges.
Magnetic fields are generated by moving electric charges, such as electrons orbiting around the nucleus of an atom.
Answer for screen readers
Magnetic fields are generated by moving electric charges, such as electrons orbiting around the nucleus of an atom.
More Information
Magnetic fields can arise from the motion of electrons in atoms, aligning atomic dipoles in materials, or from current flowing in electromagnets.
Tips
A common mistake is to think static charges can create magnetic fields; only moving charges can do so.
