  1. Question 1

    Q1. A researcher uses a technique called electromagnetic induction to separate minerals based on their magnetic properties. What is the principle behind this technique?

    • A) Electromagnetic induction causes a force on the non-magnetic minerals to move
    • B) Electromagnetic induction causes a force on the magnetic minerals to move
    • C) Electromagnetic induction separates minerals based on their electrical conductivity
    • D) Electromagnetic induction separates minerals based on their thermal properties

    Answer: Electromagnetic induction causes a force on the magnetic minerals to move

    Explanation: Electromagnetic induction causes a force on the magnetic minerals to move, allowing them to be separated from non-magnetic minerals.
