How does the strength of a bar magnet change along its length?
A bar magnet of pole strength 20 A.m. is divided into 4 equal parts by slicing it along lines parallel to length and breadth, passing through center. The pole strength of each piece is ________ A.m.
explain how will pole strength will change when a bar magnet is cut along the axis and perpendicular to the axis.
When a bar magnet is cut into two equal pieces along its length, we get two magnets each of _____ the pole strength
