Question

Magnetic induction is a
A. Scalar Quantity
B. Vector quantity
C. Both (A) and (B)
D. None of the above

Answer 1

Hint: In this question we will use the concept of scalar and vector quantity. Magnetic or electromagnetic induction is the creation of an electromotive force across an electrical conductor in a fluctuating magnetic field. Lenz's law describes the induced field's direction.

Complete step by step solution:
Magnetic induction is the creation of an electromotive force across an electrical conductor in a fluctuating magnetic field. The process of magnetic induction makes magnetic materials like steel and iron into magnets. In other words, magnetic induction is the process of making a piece of magnetic material magnetic even when it is not naturally magnetic. In this instance, the magnetic induction is a vector quantity since it follows the vector cross product and has both magnitude and direction.

Hence, the correct answer is B.

Additional Information: Physical quantities with merely magnitude and no direction are referred to as scalar quantities. These physical quantities can be explained just by their numerical value without any further guidance. These physical values can be added according to the basic algebraic rules, and in this case, only their magnitudes are added.

Physical quantities that exhibit both magnitude and direction are referred to as vector quantities. As an illustration, consider displacement, force, torque, momentum, acceleration, and velocity. A unit vector is a vector that has a magnitude value of one. The simple arithmetic rules do not apply when adding or subtracting vector values.

Note: Vector quantities are a cross product of two quantities and have direction as well as magnitude. Magnetic induction is a vector quantity and does not follow simple arithmetic rules.
