    Which statement(s) about solenoids are

    INCORRECT?
    A Magnetic field strength depends on the solenoid's diameter Correct Answer Incorrect Answer
    B A solenoid can create a uniform magnetic field when energized Correct Answer Incorrect Answer
    C Both statements are incorrect Correct Answer Incorrect Answer
    D Only statement A is incorrect Correct Answer Incorrect Answer

    Solution

    A solenoid can indeed create a uniform magnetic field within its coil when an electric current passes through. However, the magnetic field strength is independent of the solenoid's diameter, being more influenced by factors like the current and the number of turns in the coil.
