Question

The geometric length of a bar megnet having half magnetic length is 5cm

Answer 1

Explanation:

Geometric length is the measure of total length of magnet. A bar magnet consist of two equal and opposite magnetic pole separated by a small distance. ... The shortest distance between two poles is called effective length and is less than its geometric length.

Answer 2

Given :

Half of magnetic length of the bar magnet = 5 cm

To find :

The geometric length of the bar magnet .

Solution :

Half of magnetic length of the bar magnet = 5 cm

Magnetic length of the bar magnet = 5 * 2 cm

                                                          = 10 cm

Geometric length of a magnet = ( 6 / 5 )  magnetic length of the magnet

∴ Geometric length = ( 6 / 5 ) × 10 = 12 cm .

The geometric length of the bar magnet is 12 cm .
