In the previous segment, we have understood the magnetic field created due to a current- carrying conductor. In this segment, we will study the magnetic field created due to a current through a circular loop.
Magnetic Field due to a current through a Circular Loop
- French physicist Andre Marie Ampere found that the magnetic effect by a current- carrying conductor could be increased if the wire is bent in the form of a circular loop.
- Consider a long wire bend to form a circle and pass it through a cardboard such that half of the wire is above the cardboard and the remaining part of the wire is below the cardboard. Connect this setup to an electrical circuit as shown below.
Circular wire through a cardboard
- Sprinkle some iron filings on the cardboard and plug in the key to allow the current to pass through the wire.
A magnetic field is generated in the vicinity of a current-carrying conductor, and this phenomenon is known as the magnetic field due to a current through a circular loop. This field is the result of the interaction between the electric current and the magnetic field generated by the conductor. In this essay, we will discuss the nature of the magnetic field due to a current through a circular loop.
The magnetic field due to a current through a circular loop is generated by the electric current flowing through the loop. The current generates a magnetic field around the loop in a circular pattern, with the field lines pointing outward from the centre of the loop. This magnetic field will interact with the magnetic field generated by other nearby conductors and create a net magnetic field in the vicinity of the loop.
The magnitude of the magnetic field due to a current through a circular loop depends on the strength of the current and the size of the loop. As the current increases, the magnitude of the magnetic field increases, and as the size of the loop increases, the magnitude of the magnetic field decreases. Also, the direction of the magnetic field is opposite to the direction of the current flow.
The magnetic field due to a current through a circular loop can be used in a variety of practical applications. It can be used for sensing and detecting magnetic fields, for producing heat, or for inducing electrical currents in nearby conductors. It can also be used to produce electromagnetic waves that can be used for communication or for navigation.
In conclusion, the magnetic field due to a current through a circular loop is a powerful phenomenon that can be used in various applications. Its magnitude and direction depend on the strength of the current and the size of the loop, and its effects can be used to detect, produce, and induce magnetic fields.
Summary
The magnetic field due to a current through a circular loop can be determined by using the Biot-Savart Law. This law states that the magnetic field is proportional to the product of current and the distance from the current element to the point of interest. The magnetic field also depends on the angle between the current element and the direction of the field. The magnitude of the magnetic field due to a current through a circular loop can be determined by summing all the individual magnetic fields due to the current elements.
