<p>Non-eddy electromagnetic forming is a non-traditional electromagnetic forming process by directly imposing the impulse electrical current to the sheet metal instead of inducing the eddy current. The dedicated combinations of specimen and die were designed to represent different strain paths including uniaxial tension, plane strain and equal-biaxial tension. The deformation behaviors of AA5052-O aluminum alloy sheet under different strain paths have been investigated by numerical simulation of coupled electromagnetic-mechanical fields. The limit strains under different strain paths have been experimentally and numerically determined. The Marciniak–Kuczynski theoretical model embedded with the Johnson–Cook strain-rate-dependent hardening model was also used to predict the formability. The forming limit curves derived from experiment, simulation, and M–K theoretical model were confirmed to align closely with each other. Compared with quasi-static experiment results, AA5052-O aluminum alloy sheet exhibits improved formability during non-eddy current electromagnetic forming. The limit strains under uniaxial tension, plane strain, and equal-biaxial tension during non-eddy electromagnetic forming increase, respectively, by about 46, 42, and 45%.</p>
