Question

the relationship between geometrical length and magnetic length is
A. Lm=6/5 Lg
B. Lm=Lg
C. Lm=2Lg
D. Lm=5/6Lg​

Answer 1

Answer:

your answer is Lm=6/5Lg

Answer 2

Given that,

We know that,

Magnetic length $l=L_{m}$

Geometrical length $l'=L_{g}$

Magnetic length :

The distance between these two poles north and south it is called magnetic length. It is represents by $L_{m}$

Geometrical length :

The real length of the magnet it is called geometrical length. It is represents by $L_{g}$

The magnetic length is less then the geometrical length.

We need to calculate the relationship between geometrical length and magnetic length

Using relation of geometrical length and magnetic length

$L_{m}=\dfrac{5}{6}L_{g}$

Hence, The relationship between geometrical length and magnetic length is $L_{m}=\dfrac{5}{6}L_{g}$

(D) is correct option.
