Answer 1

$\underline{\underline{\Huge\mathfrak{Answer ;}}}$

Dear ,

• Geometric length =  18cm

• Pole strength (m)  =  100

• M  = ?

As  magnetic length(2l)  =  5\6 geometric length

• Magnetic length(2l)   =   5\6 .  15

                                  = 15cm

So that   2l  =  0.15m

Now  M  = m.2l

             = 100. 0.15

             = 15  Am2

Answer 2

$\huge\mathfrak {Answer:-}$

Given:-

Geometric length = $18cm$

Pole strength = $100$

M  = ?

Now,

Magnetic length = $\frac{5}{6}$ × Geometric length

Magnetic length =  $\frac{5}{6}$ $× 15 = 15\:cm$

So,

2l = 0.15 m

And,

M  = m.2l

$= 100 × 0.15$

$= 15$ Am^2
