Hint: The creation of an electromotive force across an electrical conductor in a changing magnetic field is known as electromagnetic induction.
Correct answer: Option D
Explanation of correct answer:
When a coil is moved close to a magnet and a relative motion between the two is generated by moving either the magnet or the coil, the magnetic flux connections via the coil change. An emf and, as a result, an electric current flow through the coil as a result of the change in magnetic flux.
Therefore, the correct answer is option (D).
Explanation of Incorrect Options:
During the charging by induction procedure, the charged particle is held near an uncharged conductive substance grounded on a neutrally charged material. There is no relative motion between the magnet and the coiled conductor. So, Option (A) is incorrect.
current must flow when a changing magnetic field passes through a wire coil. Due to the fact that the magnetic field remains constant. So, Option (B) is incorrect.
The process of rotating the armature of a generator counteracts the induction cause.. So, Option (c) is incorrect.
Therefore, option (A), option (B) and option (C) are incorrect. The correct answer is option (D).
