| Outline of Final Research Achievements |
The effect of the applied magnetic field from permanent magnets is investigated numerically and experimentally for the paramagnetic fluid in terms of the effective convection control and induction.It is found that the junction of multiple magnet can induce the strong magnetic force, especially two alternating magnetic pole.By the increment of the magnet was expected to enhance the effect, however, the effect becomes less due to the locally-weak magnetic force.

| Academic Significance and Societal Importance of the Research Achievements |
自然対流は身の回りの熱交換デバイスなどに利用されているが，その交換熱量には限界がありそれほど大きくないことが知られている．本研究で得られた成果は，この自然対流や熱でよどんだ流体を磁気力で駆動するために用いられるもので，永久磁石を利用することで安価かつ簡便に応用することができる技術である．したがって，現状廃棄している熱を有効に熱交換に利用できれば，熱エネルギーの効果的な回収に大きく役に立つものである．
