Question

Two identical thin bar magnets each of length l and pole strength M
are placed at right angles to each other with north pole of one
touching the south pole of other What is the net moment of the
system ?

Dear Student,

The magnetic momenta of each magnet,M1=M2=Mlwhere, l=length of barM=pole strengthThe two magnetc moment are mutually perpendicular, therefore, net magnetic moement,m=M12+M22m=Ml2+Ml2=2Ml

Two identical thin bar magnets each of length l and pole strength M are placed at right angles to each other with north pole of one touching the south pole of other. What is the net moment of the system ?
