Magnetic induction is a
Correct answer: B. Vector quantity
- A. Scalar quantity
- B. Vector quantity
- C. Both (a) and (b)
- D. None of the above
Explanation
The correct answer is that magnetic induction is a vector quantity. This is because it has both magnitude and direction. The direction of magnetic induction is the direction of the magnetic field. Scalar quantities, on the other hand, only have magnitude but no direction, which does not apply to magnetic induction. Therefore, options A and C are incorrect. Option D is incorrect as it suggests that none of the options are correct when option B is indeed correct.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
