The philosophical foundations of Aestheticism come from Immanuel Kant. He formulated the idea of "art for art's sake". He believed that art was to be enjoyed for its own beauty regardless of social or moral concerns.
An electric current has an associated magnetic field when the flow occurs in. This is also known as magnetic effect of current which has been<span> observed and quantified by </span>Ampere's Law<span>.
</span>Meanwhile, Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction<span>.

Hence, when a electric wire is placed nearby another wire carrying current, due to magnetic effect of current in the wire carrying electric current, current is induced in the wire. Hence the electric pulse and it is known as induction.
