![]() Magnetic Flux Density is a Vector Quantity. In simple terms, it is the Magnetic Flux per unit area positioned perpendicular to the Magnetic Flux. The force operating per unit current per unit length on a wire positioned perpendicular to the magnetic field is called Magnetic Flux Density(B). even the smallest magnetic element consists of a dipole or a current loop. The physical significance of Gauss law is that there is no source or sink of magnetic field lines, and isolated magnetic monopoles don’t exist i.e. Physical Significance of Gauss Law of Magnetism It means that the total number of magnetic field lines entering the surface is equal to the total number of lines exiting the surface. Let’s say Magnetic Flux through an elemental area ΔA is given by Δφ B = B. Gauss’s Law of Magnetism states that the net magnetic flux through any closed surface is zero. Maxwell is the CGS unit of Magnetic Flux.Volt-Seconds is the fundamental unit of Magnetic Flux.Weber (Wb) is the SI unit for Magnetic Flux.The following are the SI and CGS units of Magnetic Flux: Magnetic Flux UnitĪ Flux Meter is used to measure the Magnetic Flux. The Weber (Wb) or Tesla Meter Squared (Tm 2) unit of Magnetic Flux is named after German scientist Wilhelm Weber. It would be essential to find the average measurement in the event of shifting magnetic field readings across a large region. The magnetic flux through that area is then computed using the formula (10 × 10 −3 T) (0.9 m 2) = 0.0090 Wb. ![]() Assume a magnetometer probe is moved over a 0.9 m 2 region near a huge sheet of magnetic material and shows a constant reading of 10 mT. Measurement of Magnetic FluxĪ Magnetometer may be used to measure the Magnetic Flux. Weber (Wb) or Tesla Meter Squared is its SI unit (Tm 2). ![]() The Magnetic Flux is a Scalar quantity, as shown by the equation above. Φ B = B 1.dA 1 + B 2.dA 2 + B 3.dA 3 + … = ∑ all B i.dA i Magnetic Flux is Vetor or Scalar If the Magnetic Field is non-uniform, with various magnitudes and directions at different areas of the surface, the total magnetic flux across the surface may be calculated as the product of all such area elements and their respective magnetic fields. When the angle is 0°, the flux is largest as Cos 0° is 1.When the angle is 90°, the flux is lowest as Cos 90° is zero.The resultant flux depends on the glancing angle in the following manner: Where, θ is the angle between vectors A and B. It’s also necessary to consider the angle at which the field lines travel across the given surface area. The scalar product of the magnetic field and area ‘A’ gives the Magnetic Flux through a plane of area ‘A’ that is put in a Uniform Magnetic Field of magnitude B. We use the Field-Line picture of a Magnet or a set of magnets to compute the Magnetic Flux. Before we begin to appreciate his work, we must first comprehend the idea of magnetic flux, which is critical to electromagnetic induction. Faraday is largely regarded as the greatest experimental scientist of the nineteenth century, having made significant advances to science. Faraday’s breakthrough came when he discovered a simple mathematical relationship to explain a series of electromagnetic induction tests he did. The development of the concept of Magnetic Flux is attributed to Michael Faraday. ![]() θ is the Angle at which lines pass through the Area.Role of Mahatma Gandhi in Freedom Struggle.No matter how small the volume, the magnetic sources are always dipole sources (like miniature bar magnets), so that there are as many magnetic field lines coming in (to the south pole) as out (from the north pole). For a closed surface, the sum of magnetic flux is always equal to zero ( Gauss' law for magnetism). The contribution to magnetic flux for a given area is equal to the area times the component of magnetic field perpendicular to the area. HyperPhysics***** Electricity and Magnetism This unit combination has the historical name Weber (Wb). Since the SI unit for magnetic field is the Tesla, the unit for magnetic flux would be Tesla m 2. In the case of an electric generator where the magnetic field penetrates a rotating coil, the area used in defining the flux is the projection of the coil area onto the plane perpendicular to the magnetic field. It is a quantity of convenience in the statement of Faraday's Law and in the discussion of objects like transformers and solenoids. Magnetic flux is the product of the average magnetic field times the perpendicular area that it penetrates.
