Magnetic flux facts for kids
Magnetic flux (ΦB) is the number of magnetic field lines (also called "magnetic flux density") passing through a surface (such as a loop of wire). The magnetic flux through a closed surface (such as a ball) is always zero. This implies that there cannot be magnetic charges in classical electromagnetic.
The SI unit of magnetic flux is the Weber (Wb) (in derived units: volt-seconds).
The CGS unit is the Maxwell.
Magnetic flux is sometimes used by electrical engineers designing systems with electromagnets or designing dynamos. Physicists designing particle accelerators also calculate magnetic flux.
