O B. it proves Ohm's law.
O C. it is an example of an open circuit.
O D. it demonstrates electromagnetism.
SUBN

D. it demonstrates electromagnetism.

Explanation:

If a wire carrying current causes the needle of a compass to move, it is an example of electromagnetism.

The interaction between electric and magnetic fields is termed electromagnetism.

Electromagnetic interaction is usually induced between a wire and bar magnet. With right set up magnetic and electrical fields can be induced using a magnet and current carrying wire.

No because scientist are still changing there mines today so they are not correct to this day

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
