Investigation planning and methods question 1
A student investigates how the strength of the magnetic field from a solenoid changes with distance from the end of the solenoid.
The diagram shows the solenoid connected to a power supply.
The student uses a device called a Hall probe, which can be placed anywhere in the magnetic field to measure its strength at that point.
Design a suitable method for the investigation.
Your answer should include
- any extra measuring equipment needed
- details of the independent variable, dependent variable and any control variables
You may include a diagram to help your answer.
