A very long magneti is placed vertically with one pole on the table. A neutral point was found at 20 cm from the pole. What is the pole strength if the vertical component of earth's field is `0.4xx10^(-4)Wb//m^(2)`?

A very long magnet is held vertically with its south pole on a table. A single neutral point is located on the table to the

A bar magnet 30cm long is placed in magnetic meridian with its north pole pointing south. The neutral point is observed at a distance of 30cm from its centre. Calculate the pole strength of the magnet. Given horizontal component of earth's field is 0*34G .
