An optimum design of a water-cooled Bitter magnet was investigated for containerless melting experiments under a magnetic levitation condition. In order to minimize the vertical movement of a levitating sample due to the magnetic susceptibility change during a heating process, the gradient of B(partial B/partial z) along the center axis of a magnet must be large around the levitating position. Concerning the modification of an existing double Bitter magnet with 52 mm warm bore at the HFLSM, lager gradient of B(partial B/partial z) is obtained by shortening the inner coil and making the outer coil longer.
