@HarshdeepSingh8 No, no water molecules are like super small positive charge and negative charge balls, squashed together, it makes them di-polar, meaning two poles, positive and negative. Perhaps you know we're surrounded by magnets everywhere, the laptops, phones, switches, fans, remotes. Magnets produce electricity and vice versa, it's super cool. Time changing(meaning which change with time) magnetic fields 'induce' or produce charged electric field, which attracts and repels these squashed balls, making them vibrate so vigorously that their internal energy increases, making the food hot.
