| Abstract: | We measured the contact angles of Al and Sn drops on polycrystalline Al_2O_3 substrates in various high magnetic fields at different temperatures. The contact angles of both Al and Sn drops on the Al_2O_3 substrates decreased under high magnetic fields. These decreases strongly depend on the temperature,magnetic flux density, magnetic properties of the metal drops, and the reactivity of the metal drops with Al_2O_3. Our results reveal that the wetting behavior of molten metal drops on ceramics can be modified by a high magnetic field. |
