Flux is defined as (Area Perpendicular to field) x (magnetic field). If a magnet is traveling through a coil of wires. How do you figure out the area perp to the field?
Is the area of a coil defined as one coil or the all of the coils?Simon Bridge said:You use geometry.
Magnetic flux is a measure of the amount of magnetic field passing through a given surface. It is represented by the symbol Φ and is calculated by taking the dot product of the magnetic field vector and the surface normal vector.
The formula for calculating magnetic flux in Maxwell's equation is Φ = B⋅A, where B is the magnetic field and A is the area of the surface.
Magnetic flux is an integral part of Faraday's law in Maxwell's equation. It states that the induced electromotive force in a closed loop is equal to the negative rate of change of magnetic flux through the loop.
The unit of measurement for magnetic flux in Maxwell's equation is weber (Wb). It is equivalent to one volt-second and is defined as the amount of magnetic field passing through a surface of one square meter perpendicular to a magnetic field of one tesla.
Yes, magnetic flux can be negative in Maxwell's equation. This occurs when the magnetic field and surface normal vectors are in opposite directions, resulting in a negative dot product value. It simply means that the magnetic field is pointing in the opposite direction of the surface normal vector.
