Strong light-induced negative optical pressure between the two coupled gold slabs under an external magnetic field is investigated theoretically. The negative optical pressure indicates attractive interaction between the two coupled gold slabs with the air-gap cavity local resonance. Plasmon resonances lead to extremely large localized field, thereby resulting in large mutual coupling forces between the two coupled gold slabs. The light coupling into metallic microcavity can stimulate collective electron oscillations of plasmatic resonance, and cause the contraction of the negative pressure in metallic cavity wall. The light-induced negative optical pressure between the two coupled gold slabs can also be changed with the length of slab, air-gap distance, the external magnetic field, and the angle of incidence.
