Question

the magnetic length of a bar magnet is 10 cm then its geometric length is

Answer 1

Given:

Magnetic length of a bar magnet = 10 cm

To find:

The geometric length of the bar magnet

Solution:

• We know that the magnetic length is equivalent to 5/6th of geometric length.

• Thus, Magnetic length = 5/ 6 (geometric length)

                                          10 = 5/6 (geometric length)

                               10 x (6/5) = geometric length

                                          12 = geometric length

• Thus, the geometric length is 12 cm.

Answer 2

Answer:

10×6/5=12

Explanation:

as we know magnetic length=5/6 times geometric length

=6/5times magnetic length=geometric length
