Wetting angles of liquids such as deionized water and glycerol on the surface of plexiglass were measured using wetting angle goniometer. It was found that the wetting angles of the two liquids decreased with increasing magnetic field intensity. In the magnetic field of 5 T, decreases of wetting angles of two liquids were up to 10.8% and 4.0%, respectively. The phenomenon was attributed to the weakening of intermolecular interaction in liquids in a magnetic ield, reducing surface tensions of liquids and improving wetability of the two liquids.
