Answer 1

QUESTION  :-

If 0.5 T field over an area of 2 m² which lies at an angle of 60° with field . Then the resultant flux will be ?

SOLUTION  :-

GIVEN  -

Magnetic field = 0.5 tesla = 0.5 T

Area of cross section = 2 m²

Angle = 60°

here, in this question we have to find magnetic flux

Magnetic Flux  ( Ф ) =  B · A Cosθ

where,

B = Magnetic Field

A = Area of Cross section

θ  = Angle

putting the given values in the above formula.....

     Magnetic Flux ( Φ )  =  0. 5 tesla × 2 m² Cos( 60° )

→    Ф  =  1 ×  1/2 wb

→    Ф  = 0.5 weber

Therefore,

The  resultant magnetic flux is 0.50 wb

and hence,  option ( c) 0.50 Wb is correct

Magnetic Flux

The magnetic flux (often denoted Φ or ΦB) through a surface is the surface integral of the normal component of the magnetic field flux density B passing through that surface.

The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds).

The CGS unit is the maxwell.

Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.
