Difference Between Magnetic Flux and Magnetic Flux …
Main Difference – Magnetic Flux vs Magnetic Flux Density. In magnetism, several physical quantities such as magnetic flux, magnetic flux density and magnetic field strength are used to explain the behaviors or influences of magnetic fields.Some people use these terms interchangeably. But they have different and particular meanings.
Magnetic Flux
The SI unit for both these quantities are different. For electric field, it is Newton/Coulomb and for magnetic field it is tesla. Both these quantities are vector fields or quantities. The intensity of the electric field is measured using an electrometer but a magnetometer is used for measuring the intensity of the magnetic field.
