Magnetic Flux Definition
We Define Magnetic Flux as the magnetic field passing through a surface area. It is given by the product of magnetic field and the area which is perpendicular to the field. If it is not perpendicular then its perpendicular component is multiplied by the magnetic field. It is represented by phi (φ). Its equation is given as:
φ = B.A, here B is magnetic field and A is area perpendicular to the magnetic field.
If not perpendicular then we give flux equation as:
φ = B.A cosӨ.
Here Ө is angle between the normal ofthe surface and magnetic field line.
Unit of magnetic flux is Weber or Wb. Magnetic flux is zero for closed surfaces. This was proposed by gauss law.
Magnetic flux density is just like any other density. It measures that how dense or strong a magnetic field is. We define it as the amount of magnetic field lines passing through per unit surface area. This quantity is the measurement of denseness or strength of the magnetic field. It is represented by B.
Magnetic flux density depends on the density of magnetic field line or number of magnetic field lines per unit area. As shown in above figure, first surface area has less flux density and second has more as there are less magnetic field lines for first surface. Magnetic flux density does not depend on the surface area of a body. It is magnetic flux which depends on the surface area. for example if two different surface areas are place in B of same density then there will be change in flux but not in density. Magnetic flux density only depends on the density of magnetic field lines.

Magnetic Flux Density
Equation is given by: B = µ H
In above equation µ is permeability(Henry/metre) of the material and H is magnitude magnetic field.
magnetic flux density units are Wb/m2 or Tesla.Magnetic flux density id a vector and therefore has a magnitude and direction.
Free Energy Magnetic Generator is named so as we generate electrical energy for free with this and can reduce our cost in electric bills.This magnetic generator works on the principle of moving magnetic flow or the magnetic current for generation of electricity. The generator is first required to be started by an external source like motor for some time at high rotational speed. After the generator gets charged up and the energy flow establishes in the generator, the motor is removed. Now the generator generates free electricity for home use.
