The magnetometer of the previous problem is used with the same magent in `Tan-B` position. Where should the magnet be placed to produce a `37^@` deflection of the needle?

A short magnet produces a dfection of 30^(@) when placed at certain distance in tanA position of magnetometer. If another short magnet of double the length and thrice the pole strength is placed at the same distance in tabB position of the magnetometer, the deflection produced will be

A short magnet porduces a deflection of 30^(@) when placed at certain distance in tanA position of magnetometer. If another short magnet of double the length and thrice the pole strength is placed at the same distance in tan B position of the magnetometer, the deflection produced will be-

The needle of a deflection magnetometer deflects through 45^@ from north to south when the instrument is used in Tan-A position with a magnet of length 10cm placed at a distance of 25cm. (a) Find the magnetic moment of the magnet if the earth's horizontal magnetic field is 20 muT . (b) If the magnetometer is used in Tan-B position with the same magnet at the same separation from the needle, what will be the deflection?

A small magnet of magnetic moment 4A-m2 is placed on a deflection magnetometer in tan-B position at a distance of 20cm from the compass needle. At what distance from compass needle should another small magnet of moment 0.5A-m^(2) be placed such that the deflection of the needle remains zero ?

The arms of a deflection magnetometer in the tan B posittion are placed
