It is demonstrated analytically that an insulating deformable body can self-propel itself in a quiescent conducting and incompressible fluid by means of an externally applied uniform magnetic field. In particular, it is proven that such a body can accelerate persistently from rest by executing periodic controlled surface deformation. The newly found MHD self-propulsion mechanism is more pronounced compared to that existing in non-conducting fluids.
