With the development of magnetic technology, its application range. It has also expanded to the fields of biological sciences, agriculture and forestry sciences, and emerging environmental sciences. What can't we deduce from this text? ['Magnetic applications will become wider and wider.', 'Magnetic phenomena may also exist in emerging environmental sciences.', 'Magnetic phenomena in daily life.', 'Magnetic phenomena can be seen everywhere in life.']
