Magnetic lines of force due to a bar magnet do not intersect,
A bar magnet of magnetic moment `M_1` is axially cut into two equal parts. If these two pieces are arranged perpendicular to each other, the resultant magnetic moment is `M_2`, then the value of `M_1'/'M_2`
The magnetic field produced by a ................ on any point on the axial line is same as that of a bar
Earth’s Magnetic FieldThe magnetic field lines of the earth resemble that of a hypothetical magnetic dipole located at the centre of the earth. The axis of the dipole is presently tilted by approximately 11.3° with respect to the axis of rotation of the earth.The pole near the geographic north pole of the earth is called the north magnetic pole and the pole near the geographic south pole is called south magnetic pole.A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from centre of
Gauss Law in Magnetism We can write Gauss’s law for magnetostatics as `intB.dA=mu_0m`, where, `intB •dA`. is the magnetic flux and m is the net magnetic pole strength inside a closed surface. It was found that, magnetic flux through a closed surface is always zero, thus we reach at a conclusion that magnetic monopoles do not exist. A bar magnet always attain north-south poles no matter how many times it is cut into pieces.The net magnetic flux due to a bar magnet over a closed surface
