Me, i really need to know the answer of this question

Current must flow in the loop in clockwise direction to produce zero magnetic field at its centre.

Explanation:

Magnetic fields have both directions and magnitudes. Hall probes can determine the field’s magnitude. The field around the long straight wires is formed by circle loops.

The right hand rule results from this study and applies to every current segment. It states that point your thumb towards the current direction and your fingers will curl towards the magnetic field loops created due to this.

In the shown figure, due to current-carrying wire, magnetic field is in upward direction. Hence, to make that into zero the ring’s current must flow such that magnetic field will be in downward direction.

To find direction with the help of Right hand thumb rule, should curl our finger in current direction so that thumb will show us the magnetic field’s direction.

In order for magnetic field in downward direction, the ring’s current flow should be in clockwise. Ultimately, the magnetic field by wire and ring get cancel out each other.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
