Magnetic field at the centre of a circular loop of area A is B. Then the magnetic moment of the loop is (mu_(0) -permeability of the free space)

Magnetic field at the centre of a circular loop & arc

Magnetic field at the centre of circular loop of radius R is B. Magnetic moment of this coil would be _______

Magnetic induction at the centre of a circular loop of area pim^(2) is 0.1 T. The magnetic moment of the loop is ( pi_(0)= permeability of air)

IF B is the magnetic field at the centre of a circular loop of area A and its magnetic dipole moment is found to be n(BA^(m))/(mu_(0)sqrt(pi)) , then what is the value of n+m ?
