physics pyq 2024 calculate flux linkage
A circular coil of radius 10 cm is placed in a magnetic field B= (101+0:5) mT such that the outward unit vector normal to the surface of the coil is (0-6 +0.8). The magnetic flux linked with the coil is:
(A) 0-314 μWb
(B) 3-14 µWb
(C) 31.4 µWb
(D) 1-256 μWb
Magnetic Flux Linkage Calculation | Physics PYQ 2024
In this video, we solve an important previous year's question (PYQ) for the Physics 2024 exams:
A circular coil of radius 10 cm is placed in a magnetic field B = (10i + 0.5j) mT, such that the outward unit vector normal to the surface of the coil is n̂ = (0i - 0.6j + 0.8k). We calculate the magnetic flux linked with the coil and determine the correct answer from the given options:
(A) 0.314 μWb
(B) 3.14 μWb
(C) 31.4 μWb
(D) 1.256 μWb
Concepts Covered:
Magnetic flux calculation using Φ = B · A.
Dot product between the magnetic field vector and the unit normal vector.
Understanding the relationship between area, radius, and magnetic flux.
This is a great question for students preparing for competitive exams like NEET, JEE, and Class 12 board exams. Watch the full explanation and learn the step-by-step approach to solving this problem!
