A student increases the current through the electromagnet causing the metal globe to move upwards, closer to the top arm of the apparatus. Which question was the student investigating?
Understand the Problem
The question is asking how the increase in current through an electromagnet affects various forces acting on a floating globe. It requires an understanding of the relationship between current, magnetic force, and gravitational force.
Answer
How does the amount of current affect the size of the magnetic force on the globe?
The student was investigating how the amount of current affects the size of the magnetic force on the globe.
Answer for screen readers
The student was investigating how the amount of current affects the size of the magnetic force on the globe.
More Information
By increasing the current, the magnetic force increases, causing the metal globe to move upwards due to the stronger magnetic pull.
Tips
Students might confuse the magnetic force with gravitational force. It's crucial to focus on the interaction between current and the magnetic force.
