    Diamagnetic materials have permeabilities slightly less than that of free space. This means that they have a weak repulsion to magnetic fields and are slightly repelled by a magnet. Diamagnetic materials do not retain any magnetization once the external magnetic field is removed. They have no unpaired electrons and their atomic or molecular magnetic moments cancel each other out. Examples of diamagnetic materials include water, wood, and most organic compounds.

    The process of cutting internal threads by hand is known as:

    • Die working

    • Threading

    • Tapping

    • Drilling

    Correct Answer
    A. Tapping
    Explanation
    Tapping is the correct answer because it refers to the process of cutting internal threads by hand. It involves using a tap, which is a cutting tool with threads, to create threads inside a pre-drilled hole. This process is commonly used in metalworking and is essential for creating threaded holes that can be used for screws, bolts, or other fasteners. Die working, threading, and drilling are not accurate terms for this specific process.

    • A. Electromagnetic force

    • B. Induced voltage

    • C. Electromotive force

    • D. Counter-electromotive force

    Correct Answer
    A. B. Induced voltage
    Explanation
    When a conductor is exposed to a moving magnetic field, a voltage is induced in the conductor. This induced voltage is equal to the difference in charges present in the conductor. Therefore, the correct answer is b. Induced voltage.

    A reference variable is nothing but a?

    • Pointer

    • Alias

    • Function

    • Variable

    Correct Answer
    A. Alias
    Explanation
    A reference variable is an alias for another variable. It allows us to access and modify the value of the original variable using a different name. This means that any changes made to the reference variable will affect the original variable, and vice versa. In other words, a reference variable provides an alternate name for an existing variable, allowing us to work with the same data using different names.
