Hypothesis Summary
evidence exists that a changing magnetic field produces an electric current?
Develop two hypotheses to test the question
In Part I, you will design your own experiment to explore evidence that an electric current
induces a magnetic field.
In Part II, you will design your own experiment to explore evidence that a changing
magnetic field produces an electric current.
As you might guess, there are many different experiments you could design that can be
used to demonstrate the same concepts or achieve the same results. A good experiment
will be clearly laid out and concise, only containing the components necessary to test the
hypotheses. Write the hypotheses in the space below
Hypothesis 1

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

One similarity and one difference between an element and a mixture of elements

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
