Question

magnetic flux over a unit area of a surface held normal to the flux is

Answer 1

The magnetic flux through a unit area perpendicular to the field is Magnetic Flux Density. - It is defined as the amount of magnetic flux passing through per unit area of a section which is perpendicular to the direction of field.

Answer 2

Answer:

The magnetic flux per unit area perpendicular to the direction of the magnetic force: it is measured in teslas or gausses. ... Magnetic flux density also can be understood as the density of magnetic lines of force, or magnetic flux lines, passing through a specific area. It is measured in units of tesla.
