Question

The electric current flowing in a wire in the direction from B to A is decreasing. Find out the direction of the induced current in the metallic loop kept above the wire as shown.
 

Answer 1

Hint: We may make very solid electromagnets for use in several different kinds of electrical uses using wire bands twisted or woven around a soft magnetic substrate like an iron core. This use of wire coils provides an electric and magnetism interaction which gives us another type of magnetism and Electromagnetism.

Thus, the relationship between the flow of current through the conductor and the magnetic field generated around it by this current flow must be made that enables us to describe in the form of electromagnetic the relationship between electricity and magnetism.

Complete solution:
The magnetic field going through the loop due to current I according to the right-hand thumb law, is perpendicular to the paper's downward plane. The current position in the circle will be such that this field will be expanded. The direction of the induced current in the metallic loop kept above the wire is clockwise.

Note: Electromagnetism happens when a single conductor, such as a length of the wire or cable, moves through the electrical current and a magnetic field around the entire conductor is generated. The tiny magnetic field formed by the drivers has a specific direction in which both the "North" and the "South," generated by the electrical current direction that passes through the driver, are determined.

The direction of rotation of this magnetic field depends on how the current passes through the conductor and the magnetic field generated is greater in the immediate vicinity of the middle of the current conveyor.
