What is the difference between magnetic flux and magnetic field?

Expert Answer
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires,
or microscopic currents associated with electrons in atomic orbits.
The magnetic field B is defined in terms of force on moving charge in the Lorentz force law F = q × v × B.
The SI unit for magnetic field is the Tesla.
Magnetic flux Φ is the product of the average magnetic field B times the perpendicular area ΔA that it penetrates.
Φ = B × ΔA
It is a quantity of convenience in the statement of Faraday's Law and in the discussion of objects like
transformers and solenoids.
SI unit of magnetic flux is Weber (Wb ).
Magnetic field is magnetic Flux density. Hence 1 Tesla = 1Wb/m2
