A perfect magnetic conductor is defined to be a material for which the tangential component of the magnetic field is zero at the surface.

A perfect magnetic conductor, also known as a magnetic wall or magnetic boundary, is an idealized concept in electromagnetism. It is a material that exhibits a specific behavior with respect to the magnetic field. Let's understand the definition of a perfect magnetic conductor and why option 'A' is the correct answer.

Understanding the Definition:
- A perfect magnetic conductor is a material that does not allow the penetration of magnetic field lines through its surface.
- It is an idealized material that can redirect all the incident magnetic field lines in such a way that they become tangential to its surface.
- In other words, the tangential component of the magnetic field must be zero at the surface of a perfect magnetic conductor.

Explanation of Option 'A' being the Correct Answer:
The given options are:
a) A tangential component of the magnetic field is zero at the surface.
b) A tangential component of the electric field is zero at the surface.
c) The normal component of the magnetic field is non-zero.
d) The normal component of the electric field is non-zero.

To understand why option 'A' is correct, let's analyze the other options:

b) A tangential component of the electric field is zero at the surface:
- This option is incorrect because it refers to the behavior of the electric field, not the magnetic field. The question specifically asks about the magnetic field behavior.

c) The normal component of the magnetic field is non-zero:
- This option is incorrect because a perfect magnetic conductor redirects all the magnetic field lines to be tangential to its surface. Hence, the normal component of the magnetic field becomes zero.

d) The normal component of the electric field is non-zero:
- This option is incorrect because it refers to the behavior of the electric field, not the magnetic field. The question specifically asks about the magnetic field behavior.

Hence, the correct answer is option 'A', i.e., a perfect magnetic conductor is defined as a material for which the tangential component of the magnetic field is zero at the surface.
