A permanent bar magnet is cut
longitudinally along its axis

If a permanent bar magnet is cut along its length into two equal parts, what will be the pole - strength and magnetic moment of each part ?

A permanent bar magnet is cut transverse to its axis , into two equal parts. What will be the magnetic moment of each part relative to that of the initial uncut magnet ?

If a permanent bar magnet is cut along its breadth into two equal parts , what will be the pole - strength and magnetic moment of each part ?

A short bar magnet placed on a horizontal plane has its axis aligned along the magnetic north- south direction . Null points are found on the magnet . The earth's magnetic field at the place is 0.36G . What is the magnet at the total magnetic field on the normal bisector of the same distance as the null points (i.e., 14 cm) from the centre of the magnet (at null points , field due to a magnet is equal and opposite to the horizontal component of earth's magnetic field . )

An electromagnetic wave is propagating along positive z-axis. At any moment, if the direction of the magnetic field at a point be along positive x-axis, what will be the direction of the electric field at that point?

A small bar magnet is place horizontally in the magnetic meridian with its north pole pointing south ,. A neutral point is formed on the axis of the bar magnet at a distance of 24 cm from its south pole. If the horizontally component of earth's magnetic field is 0.18xx10^(-4) what will be the magnetic field at a distance of 20 cm north of the south pole?
