Adventures Of Superman #425

Emil Hamilton first asks Lex Luthor to publicize his machine that can capture Superman. Lex threatens to sue if the blueprints aren’t handed in. After Emil is forced to leave, Henry Wyatt visits his home and makes an agreement to fund him. The perfected prototype that Emil presents is hacked by cut wires from an unknown person. The magnetic force protected the man in it from bullets, but the man died from the magnetic field disappearing. Meanwhile, Superman is against a machine run by terrorists. Superman fights the machine until Emil, desperate for publicity, makes a magnetic box around Superman and the machine.
