Derivation. Where, B = Magnetic Field, A = Surface Area, and θ = Angle between the magnetic field and normal to the surface. Therefore, Magnetic Flux is dimensionally represented as [M1 L2 T-2 I-1].
What is magnetic flux density dimension?
Magnetic Flux Density and Magnetic InductionCharacteristicNotesMetric (SI) Dimensionsmass × time-2 × electric-current-1These are the dimensions of the “magnetic flux density” quantity in SI units. There are other unit systems used in electromagnetics that may assign different dimensions.Ещё 5 строк
How is the direction of magnetic flux determined?
The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.
What is the SI unit and dimension of magnetic flux?
1. Magnetic flux has the dimension mass length squared per time squared electric current (ML2T2I). The SI derived unit of magnetic flux is the Weber, which is defined as a volt second.
What is magnetic flux density formula?
The magnetic field vector B is defined by the force it would apply to a charge moving in it. B = F/qv, so the units are (N *s) / (C *m), which we call a Tesla, or T. This is also called flux density. Flux is then given by B*A, so it is in T*m^2, which we also call a Weber.
What is motional EMF?
About Transcript. An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B.
Does magnetic flux have a direction?
The general direction for the magnetic flux flow is from the North ( N ) to the South ( S ) pole. … Lines of force have a definite DIRECTION from North to South. Lines of force that are close together indicate a STRONG magnetic field. Lines of force that are farther apart indicate a WEAK magnetic field.
Does flux have direction?
These fluxes are vectors at each point in space, and have a definite magnitude and direction. Also, one can take the divergence of any of these fluxes to determine the accumulation rate of the quantity in a control volume around a given point in space. For incompressible flow, the divergence of the volume flux is zero.
When magnetic flux is maximum?
The magnetic flux through the plane of the coil has its maximum value when this plane is perpendicular to the magnetic field lines between the poles. As the coil turns and the plane of the coil becomes parallel to the field lines, the flux becomes zero.
What is the dimension of flux?
Therefore, Magnetic Flux is dimensionally represented as [M1 L2 T-2 I-1].
What is SI unit of magnetic flux?
The SI derived unit of magnetic flux density is the tesla, which is defined as a volt second per square meter. … A gamma is defined as tesla.
