A wire carrying current is bent in the form of a circular loop.
Then the magnetic field around each portion of the wire will be
A. parallel to the plane of the wire.
B. perpendicular to the circumference of the wire.
C. parallel to half portion and perpendicular for the other half.
D. none of above.
Answer: A
Share your understanding of this question with the correct explanation.
When a wire carrying current is bent in the form of a circular loop, the magnetic field around each portion of the wire will be parallel to the plane of the wire. Therefore, the correct answer is A: “parallel to the plane of the wire.”
Here’s a further explanation:
When current flows through a wire, a magnetic field is created around the wire. The direction of the magnetic field can be determined using the right-hand rule. If you imagine grasping the wire with your right hand, such that your thumb points in the direction of the current, then the curled fingers will represent the direction of the magnetic field around the wire.
In the case of a circular loop, the current flows in a circular path. If we consider a specific portion of the wire in the loop, the current direction will be tangent to that portion. By applying the right-hand rule, we can determine that the magnetic field lines around that portion of the wire will be parallel to the plane of the wire.
This means that the magnetic field lines will lie in the same plane as the circular loop. The magnetic field lines will form concentric circles around the wire, with the wire lying at the center of these circles. The magnetic field lines will be parallel to the plane of the wire throughout the loop.
In conclusion, when a wire carrying current is bent in the form of a circular loop, the magnetic field around each portion of the wire will be parallel to the plane of the wire.
