A very long magnet of pole strength `4 Am` is placed vertically with its one pole on the table. The distance form the pole, the neutral point will be formed is `(B_(H)=4xx10^(-5)T)`

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 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 bar magnet of length 14 cm is placed in the magnetic meridian with its north pole pointing towards the geographic north pole. A neutral point is obtained at a distance of 18 cm from the center of the magnet. If B_(H)=0.4 G, the magnetic moment of the magnet is (1G = 10 ^(-4) T)

A bar magnet of length 8 cm and having a pole strengh of 1.0 A m is placed vertically on a horizontal table with its south pole on the table. A neutral point is found on the table at a distance of 6.0 cm north of the magnet. Calculate the earth's horizontal magnetic field.
