Question

define magnetic field and flux density .what is the unit of flux density?

Answer 1

Magnetic field - It is the region around any magnetic material or moving charge within which force of magnetism act .

flux density- It is the amount of flux (magnetic ,electric and other) passing through a unit area.

The unit of flux density =  tesla or webers/m^2

Answer 2

Answer:

☸magnetic flux :- the magnetic flux is defined as the number of magnetic field lines crossing an area (A). if thita is the angle between the direction of the field and normal to the area

☸magnetic flux density :- it is defined as the magnetic flux (associated normally) per unit area.

I. e. magnetic flux density = flux/area

si unit of magnetic flux :- Weber (Wb) Or T. m²

CGS unit of magnetic flux :- Maxwell

$1weber = {10}^{8 } maxwell$

Dimensional formula of magnetic flux:- {ML²T-²A-¹}
