Question

Complete and label the following diagram.

Answer 1

Hint:In order to answer the above question, we will analyse the circuit given in the question. We will understand the circuit and label the components of the circuit. We will be discussing the phenomenon that is happening in the circuit and define each of its parts in detail.

Complete answer:
As we can see from the figure given in the question, there is a circuit consisting of a current carrying loop connected to a battery and a resistor. There is an ammeter connected in series.And we have field lines over the plane that is passing through the conducting loop and is also perpendicular to the loop.

From all these details, we can conclude that the above circuit is explaining the phenomenon of the production of magnetic fields due to a current carrying loop. And this phenomenon is explained by Ampere's circuital law. Ampère's circuital law in electromagnetism connects the integrated magnetic field around a closed loop to the electric current flowing through it.

We know that a magnetic field is created by an electric current. The magnetic field around a wire can be visualised as a pattern of circular field lines. A compass, as shown by a long straight current-carrying wire in, can be used to investigate the direction of a magnetic field. The magnitude of the field can be determined using Hall probes. This research uncovers a new version of the right hand rule that applies to any current segment: point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops it creates.

According to the theory above, we can conclude that the field lines that are expressed on the plane perpendicular to the current carrying loop gives the magnetic field lines. And the direction of these magnetic field lines as well as the current can be determined by the Right Hand Thumb Rule. The remaining components in the circuit are the battery, a resistor and an ammeter to find the magnitude of current.

Note: It is important to keep in mind that the diagram we are asked to label should be examined properly. We should always know the direction of the current in order to determine the direction of the magnetic field. It is also very important to examine if the circuit is closed to be able to carry out a circuit. One should also know about the basic electronic components used in a circuit.
