Structural properties like the total energy, ionisation potential, excitation energies and transition probabilities for the first four magnetic dipolar (M1) excitations $1s^{2}$:$^{1}$S$^{e}\rightarrow1sns$:$^{3}$S$^{e}_{1}$ and magnetic quadrupolar (M2) excitations $1s^{2}$:$^{1}$S$^{e}\rightarrow1snp$:$^{3}$P$^{o}_{2}$ (n = 2,3,4,5) of helium atom endohedral to a fullerene cage have been estimated. Time dependent coupled Hartree-Fock(TDCHF) theory within variational scheme has been adopted for the detailed study of the excitation properties. The structural properties have been estimated by introducing an effective potential replacing that for the free atom, mimicking the fullerene environment which may be neutral, positive or negatively charged. Interesting behaviour of the properties of the confined He atom have been observed with respect to nature of the charge on fullerene cage. Results for the free He atom agree well with those available in the literature while those for the confined system have been reported for the first time.
