AP EAMCET · PHYSICS · Magnetic Properties of Matter
If the given figure shows the relation between magnetic field (B-along \(y\)-axis) and magnetic intensity ( H -along x -axis) of a ferromagnetic material, then the point that represents coercivity of the material is
- A \(P\)
- B Q
- C R
- D S
Answer & Solution
Correct Answer
(C) R
Step-by-step Solution
Detailed explanation
The point where the magnetic field (B) becomes zero after the material has been magnetized is called the coercivity. From the given figure, at point R, the magnetic field (B-along y-axis) is zero, while there is a negative magnetic intensity (H-along x-axis). Therefore, the…
