A magnetic needle of pole strength `'m'` is privoted at its centre. Its `N-`pole is pulled eastward by a string. Then the horizontal force required to produce a deflection of `theta` from magnetic meridian `(B_(H) "horizontal componet of earths magnetic field")`

What is the value of the horizontal component of the earth's magnetic field at the poles?

What is the value of horizontal component of the earth's magnetic field at the magnetic poles?

A magnetic dipole of magnetic moment 6Am^(2) is lying in a horizontal plane with its north pole pointing toward 60^(@) East of North. Find the net horizontal magnetic field at a point· on the axis of the magnet 0.2m away from it. Horizontal Component of earth field at this place is 30 mu T .

A 30 cm long bar magnet is placed in the magnetic meridian with its north pole pointing south. The neutral point is obtained at a distance of 40 cm from the centre of the magnet. Pole strength of the magnet is (The horizontal component of earth’s magnetic field is 0.34 Gauss)

A short bar magnet with its north pole facing north forms a neutral point at P in the horizontal plane. If the magnet is rotated by 90^(@) in the horizontal plane, the net magnetic induction at P is (Horizontal component of earth's magnetic field =B_(H))

A short bar magnet with its north pole facing north forms a neutral point at P in the horizontal plane. If the magnet is rotated by 90^(@) in the horizontal plane, the net magnetic induction at P is (horizontal component of earth's magnetic field = B_(H) )

A short bar magnet with its north pole facing north forms a neutral point at P in the horizontal plane. If the magnet is rotated by 90^(@) in the horizontal plane, the net magnetic induction at P is (Horizontal component of earth's magnetic field =B_(H))
