A hybrid magnet is a combined system of an outer superconducting magnet and an inner high-power water-cooled magnet, generating continuous high magnetic fields. A small Bitter coil to be used for the latter magnet has been designed, constructed and tested up to the DC electric power of 3 MW and the deionized-water flow rate of 130 m^3/h. According to expectations, the field produced in a clear bore of 32 mm diameter has reached 12.4 T without an excessive temperature rise of the coil
