The magnetic moment of para hydrogen is __________

Define magnetic moment.

Show that the electron revolving around the nucleus in a radius 'r with orbital speed 'r' has magnetic moment evr/2. Hence, using Bohr's postulate of the quantization of angular momentum, obtain the expression for the magnetic moment of hydrogen atom in its ground state.

Three similar bar magnets are placed to form an equilateral triangle as shown in the figure . The magnetic moment of each magnet is M . What is the magnetic moment of the system ?
