There is more magnetic force in that region on a particle.
Faraday, proposed lines of flux and lines of force.
Magnetic flux lines travel from the north pole of a magnet to the south pole.
The lines of flux are crowded at the ends of magnets, this phenomena is called fringing.
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface.
Superconductors are the materials most affected by magnetic flux lines. In a superconducting state, they expel magnetic fields through the Meissner effect, leading to the formation of quantized flux lines (or vortices) in type-II superconductors when exposed to external magnetic fields. These flux lines can influence the material's properties, including its critical current and magnetic behavior, making superconductors unique in their interaction with magnetic fields.
That is where the imaginary "flux lines" are concentrated.
By cutting lines of magnetic flux through an electromagnet
Magnetic flux
magnetic flux lines.
Electro magnetic flux which is in maxwells and gauss.
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
