  1. Question 1

    Electromagnetism is the branch of physics that deals with the interactions between:

    • Asound and heat
    • Belectric and magnetic fields
    • Clight and sound only
    • Dmass and energy only
    Show answer

    Answer: B

    Electromagnetism deals with interactions between electric and magnetic fields.

  2. Question 2

    Moving charges, like an electric current, create:

    • Amagnetic fields
    • Bonly sound
    • Conly heat
    • Dgravity
    Show answer

    Answer: A

    Moving charges such as an electric current create magnetic fields.

  3. Question 3

    Even light is an:

    • Aelectromagnetic wave
    • Bsound wave
    • Cwater wave
    • Dmechanical wave only
    Show answer

    Answer: A

    The text states that even light is an electromagnetic wave.

  4. Question 4

    What does a steady electric current in a conductor generate around it?

    • AElectric field
    • BLight
    • CMagnetic field
    • DSound waves
    Show answer

    Answer: C

    A steady current in a conductor generates a magnetic field B around it.

  5. Question 5

    Who stated that a steady electric current in a conductor generates a magnetic field around it?

    • AHans Christian Orsted
    • BNewton
    • CCoulomb
    • DOhm
    Show answer

    Answer: A

    The text attributes this to Hans Christian Orsted.
