The correct answer (sample response) is:

If a magnetic or electric field is present, materials that generate these fields will interact by attracting or repelling each other because of their magnetic or electric properties.

The statement is a hypothesis about the effects of magnetic and electric fields. Use the format of "if...then...because..." and be sure to answer the lesson question: "How can magnetic and electric fields be demonstrated?"

Include the following in your hypothesis:

• The "if" part of your hypothesis refers to the presence of an electric or magnetic field.

• The "then" part of your hypothesis refers to a measurable attraction or repulsion.

• The "because" portion of your hypothesis connects the ideas of electromagnetic properties.
