select the correct answer. which of the following actions cannot induce voltage in a wire? a. moving a coil of wire near a magnet b. moving a magnet near a coil of wire c. changing a current in a nearby coil of wire d. changing the magnetic field around the coil of wire e. moving a wire parallel to a magnetic field

Answer

Brief Explanations:

According to Faraday's law of electromagnetic - induction, an electromotive force (emf) or voltage is induced in a conductor when there is a change in the magnetic flux through the conductor. Moving a coil of wire near a magnet (A), moving a magnet near a coil of wire (B), changing a current in a nearby coil of wire (C) (which changes the magnetic field around it), and changing the magnetic field around the coil of wire (D) all cause a change in magnetic flux through the wire. However, when a wire is moved parallel to a magnetic field, the magnetic flux through the wire does not change.

Answer:

E. moving a wire parallel to a magnetic field
