Question

design an experiment that would allow you to observe magnetic fields and test how the magnetic field lines change under various conditions. Create a list of materials and write a procedure. Sketch models to show your expected results for each condition. Be sure to label your diagrams. Explain what you expect to observe using your knowledge of magnets and magnetic field lines.

Answer 1

Suggested experiment:

A compass is an instrument that contains a magnetized pointer which shows the direction of the magnetic north.

To observe magnetic field lines, an array of several compasses can be placed on top of a table. When undisturbed, they will align with the Earth's magnetic field.

When a magnet is placed near the array of compasses, they will change their direction according to the magnetic field of the magned. You can try with different magnets in different positions to see how the compasses respond to the presence of the magnet. Magnetite magnets are usually not very strong. A stronger magnet could be a neodymium magnet. You could also use a coil to generate the magnetic field and play with the array of compasses.

Develop this idea to complete the task.
