Difference Between Magnetic Field and Magnetic Flux

Main Difference –Magnetic Field vs. Magnetic Flux

magnetic field and magnetic liquefy both refer to properties of magnets. The main difference between magnetic field and magnetic flux is that magnetic field is a region where magnetic poles and moving charges experience a force. sometimes, the terminus magnetic plain may be besides used to refer to the quantity charismatic field strength. Magnetic flux is a measurement of how much magnetic field passes through an area .

What is a Magnetic Field

A magnetic field is a region in space where magnetic poles and moving charges experience a military unit ( assuming no electric plain is present because they can besides exert forces on charges ). The stronger the magnetic plain, the stronger is the military unit felt. A magnetic field can be depicted using magnetic field lines. A stronger magnetic field has its charismatic field lines drawn close together. An arrowhead can be drawn on the magnetic field tune so that the battlefield lines orient along the management of the way taken by a north pole placed in the magnetic field. The form of charismatic field lines can be obtained by putting iron filings in a magnetic field and allowing them to line up .

If the term “ magnetic field ” is used to refer to a quantity rather than a region, it is most likely referring to the magnetic field force. The SI unit for measuring magnetic field lastingness is the tesla (T). The Earth ’ s magnetic field potency changes from place to place, but it is in the order of microteslas. Magnets used in MRI machines in hospitals tend to produce magnetic fields of a few tesla, and the strongest magnetic plain we have managed to create is about 90 T .

What is Magnetic Flux

magnetic liquefy is a measurement of how much magnetic field passes through an area. therefore, this quantity depends not merely on the magnetic field strength but besides on an area. A simplify explanation for magnetic flux is that the magnetic flux gives the “ issue ” of charismatic field lines passing through the area .
however, the courtly definition for charismatic flux is given using vector calculus. In this definition, the magnetic blend \Phi is found by integrating the magnetic field over a open :
\Phi =\int \vec{B}\cdot d\vec{A}
For a undifferentiated charismatic field of force B casual vertical to an area A, this simplifies down to :
\Phi=BA

The unit of magnetic flux is, then, T m2. The SI whole for measuring magnetic flux is the weber ( Wb ), with 1 Wb = 1 T m2 .
Gauss’s law of magnetism says that the full magnetic flux through a close open is 0. This means that magnetic field lines form close loops, and therefore, that a north perch can not exist without a south perch and vice versa. however, there are theories that predict the being of alleged “ magnetic monopoles ”, although no experiment has however discovered them .

Difference Between Magnetic Field and Magnetic Flux

What it Describes

Magnetic field describes a region where a magnetic force can be felt .
Magnetic flux describes how much magnetic battlefield passes through an area .

Dependence on Area

Magnetic field depends entirely on the attraction that produces it .
Magnetic flux depends not lone on the attraction that produces the field but besides on the size and orientation of an area .
