Embodiments of the present disclosure provide a magnetic-field focusing apparatus including a magnetic-field generating unit including a plurality of transmit coils and configured to receive a transmit pulse to be applied to each of the transmit coils and to generate a magnetic field, and a pulse generating unit configured to calculate a magnitude of a current to be applied to each of the transmit coils by using structure information based on a positional relationship between a focusing point for focusing a magnetic flux and the transmit coils and to generate the transmit pulse to be applied to each of the transmit coils based on the magnitude of the current. A magnetic-field receiving apparatus is also provided for the magnetic-field focusing apparatus.
