A thin rod 30 cm long is uniformly magnetised and its period of oscillation is 4 s . It is broken into three equal parts normal to its length. The period of oscillation of each part is

Two magnets of a magnet is 16 cm . Its pole strength is 250 milli.amp.m . When it is cut into four equal pieces parallel to its axis, The magnetic length, pole strength and moments of each piece are: (respectively)

A thin bar magnetic is cut into two equal parts by cutting is perpendicular to ties length. What is the new magnetic moment of each part ? What is the time - period of each part as compared to that of the original magnet if if vibrated in the same field ?
