How to calculate magnetic flux linkage. This magnetic flux calculator calculates the magnetic flux of an object based on the magnitude of the magnetic field which the object emanates and the area of the object according to the formula fba if the magnetic field is at a 900 angle perpendicular to the area of the object. This process is defined to be electromagnetic induction. Ba this is when b is perpendicular to a so the normal to the area is in the same direction as the field lines.
To calculate the strength of a magnetic force on a wire you must find the magnetic flux density. You can think of flux as being the amount of magnetic field that youve swept through not just the area you swept through but area x field strength. This is measured in a unit called tesla.
As the proportionality constant is equal to 1 for a uniform rate of change of flux linkage this can be written as. In the most general form magnetic flux is defined as fb abda f b a b d a. Any change in magnetic flux f induces an emf.
F ba units of flux. The magnetic flux through an area a in a magnetic field of flux density b is given by. Across the coil equal in magnitude to the rate of change of flux linkage.
F b a cos a where f is the magnetic flux webers b is the magnetic field teslas. Magnitude of induced emf. Lines are drawn to show the direction on a magnets north.
F ba cos o where b is the magnetic field strength over an area a at an angle o with the perpendicular to the area as shown in figure 5. The following equation can be used to calculate a magnetic flux. It is the integral sum of all of the magnetic field passing through infinitesimal area elements da.
N df dt where df is the change of flux in time dt. Magnetic flux the magnetic field strength b multiplied by the area swept out by a conductor a is called the magnetic flux f. Flux linkage can be calculated by magnetic flux number of turns on coil and according to faradays law of electromagnetic induction a changing flux linkage results in the induction of an emf.
Experiments revealed that there is a crucial quantity called the magnetic flux f given by.
