Assertion (A): Magnetic flux is a vector quantity. Reason (R): Value of magnetic flux can be positive negative or zero.

Options

  1. ABoth A and R are true and R is a correct explanation for A
  2. BBoth A and R are true but R is not a correct explanation for A
  3. CA is true, R is false
  4. DA is false, R is true

Correct answer

D. A is false, R is true

Step-by-step solution

Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area. Here, the area under consideration can be of any size and under any orientation with respect to the direction of the magnetic field.
