PhysicsEasysingle choice

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

Options:

Answer:

Solution:

Magnetic dipole moment is a vector quantity.

$M_{r e s} = \sqrt{{(\sqrt{3} M)}^{2} + M^{2}}$

$M_{r e s} = 2 M$
