Four magnets of magnetic momnets `M,2M,3M` and `4M` are arranged in the fome of a square such that unlike poles are in contact. Then the resultant magnetic moment will be

Three identical bar magnets each of magnetic moment M are arranged in the form of an equilateral triangle such that at two vertices like poles are in contact. The resultant magnetic moment will be

Three identical bar magnets each of magnetic moment M are arranged in the form of an equilanteral triangle such that at two vetices like poles are in contact. The resultant magnetic moment will be

Three magnets of same length but moments M,2M and 3M are arranged in the form of an equilateral triangle with oppositive poles nearer, the resultnat magnetic moment of the arrangement is

Two identical bar magnets having magnetic moments 2p_(m) and3p_(m) are kept one over the other in such a manner that their opposite poles are in contact . Determine the resultant magnetic moments in each case .

Select the correct answer. a) When 'n' identical magnets are arranged in the form of closed polygon with unlike poles nearer, the resultant magnetic moment is zero. b) If one magnet is removed from the polygon, the resultant magnetic moment becomes 'M' . c) If one magnet is reversed in the polygon, the resultant magnetic moment of combination becomes 2M

The magnetic moment of a bar magnet is 0.256amp.m^(2) . Its pole strength is 400 milli amp. m . It is cut into two equal pieces and these two pieces are arranged at right angles to each other with their unlike poles in contact (or like poles in contact). The resultant magnetic moment of the system is

A bar magnet of magnetic moment M_(1) is axially cut into two equal parts. If these two pieces are arranged perpendiucular to each other, the resultant magnetic moment is M_(2) . Then the vale of (M_(1))/(M_(2)) is
