Concept:The magnetic effect of current produces motion or sound in devices that use electromagnetism.Explanation:A lead acid accumulator stores and releases electrical energy through chemical reactions.It does not rely on the magnetic effect of current to work.An electric bell uses an electromagnet to attract and release a hammer.A moving coil galvanometer uses the magnetic force on a current-carrying coil to deflect a needle.A telephone receiver uses an electromagnet to vibrate a diaphragm and produce sound.Therefore, the device that does not use the magnetic effect of current is the lead acid accumulator.Answer:A. Lead acid accumulator
