Saurav Pandey, a class 12 student, conducted an experiment to determine the effect of temperature on the strength of a magnet. He hypothesized that magnetism would decrease with increasing temperature, following an exponential curve. The procedure involved measuring the mass of paperclips attracted to a magnet at various freezer and oven temperatures. Observation showed magnetism increased as temperature decreased from -21C to 0C, and decreased as temperature increased from room temperature to 50C. The conclusion was that cold strengthens magnets by slowing atomic movement and domain alignment, while heat weakens them by increasing movement and disrupting domains.
