It is popularly demonstrated using by dropping a magnet down a copper tube.
It explains why an aluminum block would fall very slowly when dropped in an MRI. It is popularly demonstrated using by dropping a magnet down a copper tube. According to this law of electromagnetism, a closed wire loop will have a  clockwise electric current when a magnet approaches it south-pole-first. A consequence of the conservation of energy, it states that a change in magnetic flux must produce a current such that the magnetic field associated with the current  opposes the original field, according to the right-hand rule. FTP, name this law that gives the direction of a current  induced by a changing magnetic flux.
