A changing magnetic flux produces around itself as induced:

Explanation

According to Faraday's law of electromagnetic induction, a changing magnetic flux induces an electromotive force (EMF) or voltage in a conductor. This induced EMF creates an electric field around the region where the magnetic flux is changing. This phenomenon is the basis for the generation of electric currents in devices like generators and transformers.- A) Magnetic field: While a changing magnetic flux can influence the magnetic field in the vicinity, the primary induced effect is the creation of an electric field.- C) Electromagnetic force: The induced effect is an electromotive force (EMF) or voltage, not a direct electromagnetic force.- D) Artificial gravitational field: Changing magnetic flux does not produce an artificial gravitational field. Gravitational fields are associated with mass, not with magnetic phenomena.So, the correct answer is B) electric field, as a changing magnetic flux induces an electric field around itself.
