Vedclass · Answer

(D) $1$. According to Faraday's law of electromagnetic induction, an induced electromotive force $(emf)$ is produced in a coil whenever there is a change in the magnetic flux linked with it.$2$. Relative motion between the coil and the magnet is necessary to change the magnetic flux linked with the coil.$3$. In cases $(a)$, $(b)$, and $(c)$, there is relative motion between the coil and the magnet, so the magnetic flux changes and the galvanometer pointer deflects.$4$. In case $(d)$, there is no relative motion between the coil and the magnet, so the magnetic flux remains constant and there is no deflection in the galvanometer.$5$. Therefore, statement $(d)$ is the only wrong statement regarding the condition for deflection.
