Electricity’s interrelationship with magnetism

Electricity’s interrelationship with magnetism is described by the term electromagnetism. Electromagnetism has been the target of study and research throughout the years. Furthermore, one can hardly think of the world without electricity. Electricity and magnetism have improved human life in many spheres ranging from lighting, cooling and heating houses to running computers and television sets among many other electric appliances used today (Bloomfield 253).

One of the common uses of the electromagnetism is storage and retrieval of information. Since the nineteenth century magnetic fields have been applied to record, store and play back sound. Between 1930s and 1940s scientists and engineers invented magnetic tapes. Sound recordings were made on phonographs. Magnetic tapes were made using flexible substance covered with a thin stratum of magnetic particles. Information is written on and read from the tape using a gadget known as the head. The head is a small electromagnet having a wire coil wound on a small magnet
