What is a magnetic field and how does it work?
Understand the Problem
The question is providing information about magnetic fields, describing their characteristics and interactions with magnetic materials.
Answer
Magnetic fields are regions where magnetic forces act, produced by moving charges and particle spins.
A magnetic field is the space around a magnet where its magnetic influence is felt, produced by moving electric charges and the intrinsic magnetic moments of elementary particles. It attracts magnetic materials and can cause attraction or repulsion between magnets.
