Abstract: An apparatus for generating tactile sensation by using a magnetic field, includes: a first magnet and a second one which are placed across a target as a subject to provide tactile sensation; and a first electromagnet placed between the target and the first magnet; wherein a strength of the whole magnetic field between the first and the second magnets is allowed to be adjusted by adjusting at least either of a direction and a strength of a magnetic field arising from the first electromagnet to control the strength of the force with which the target is pressed by the first and the second magnets. Because a magnet itself that generates a magnetic field without any complicated mechanical components may perform a function as an actuator that generates tactile sensation, the apparatus for generating tactile sensation may become simple, light and compact.
