Question

What do you mean by Magnetic Fields?

Answer 1

1. The magnetic field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts.
2. A charge in motion can generate a magnetic field.
3. In physics we use $\mathrm{B}$ or $\mathrm{H}$ as a symbol of the magnetic field.
4. The SI unit of the magnetic field is Tesla $\left(\mathrm{T}\right)$.
5. The magnetic field emits from the north pole and terminates in the south pole.
6. Typically a magnetic field can be illustrated in two different ways
   6.1 Magnetic Field Vector: The magnetic field can be mathematically described as a vector field.
   6.2 Magnetic field lines: Magnetic field lines are an alternative way to represent the information contained within a magnetic vector field. Magnetic field lines are imaginary lines.
7. When a magnetic field is present, these domains align themselves in the direction of the outside magnetic field, making non-magnetized material into a miniature magnet and two magnets with opposing poles are attracted to one another
