Why do material scientists study magnetic and electrical properties? Material scientists study magnetic and electrical properties because these properties are crucial in various fields such as electronics, telecommunications, energy storage, and medical devices. Electromagnets are mainly used in material science to create fancy light displays and artistic installations, not for practical applications such as magnetic levitation or material separation. Material scientists don't study magnetic and electrical properties. They study electrical properties to improve the taste and texture of food products by controlling the conductivity of ingredients
