Question

what is the flux density of a magnetic field of a cross sectional area 20cm having a flux of 2mwb?

Answer 1

Answer:

 A magnetic circuit is made up of one or more closed loop paths

containing a magnetic flux ϕ (= magnetic field/flux density B ×

cross-sectional area A).

 The flux is usually generated by permanent magnets or

electromagnets and confined to a path by magnetic cores consisting

of ferromagnetic materials like iron, although there may be air gaps

or other materials in the path.

 Magnetic circuits are employed to efficiently channel magnetic fields in

many devices such as electric motors, generators, transformers,

relays, solenoids, loudspeakers, hard disks, MRI machines
