Answer:
The mmf required is
×
A
Explanation:
The Magnetomotive force (mmf) is given by the formula below

where
is the Magnetomotive force (mmf)
is the Magnetic field strength
is the magnetic length
The magnetic permeability μ is given by
μ = 
Where
is the Magnetic flux density
and
is the Magnetic field strength
From the question,
= 1.2Wb/m^2
μ = 1600m
From μ = 
∴
μ

×
A/m
Now, for the Magnetomotive force (mmf)

From the question
= 1.5 m
∴
×
× 
×
Hence, The mmf required is
×
A
