Leisha is conducting an investigation about the strength of the forces between an electromagnet and other magnetic objects. She constructs an electromagnet from a battery, nail, and coils of wire, as shown in the diagram. Leisha hangs a piece of iron from a string and brings it near the sharp end of the nail. She repeats her process with a bar magnet. Leisha’s initial observations are shown in the table. Based on the provided data table, what was Leisha most likely investigating? Choose the letter of the correct answer.

Hello. You didn't show the table or the answer options, but according to the experiment that Leisha can say she is investigating the magnetism capacity in the homemade magnet she built.

Explanation:

Leisha built a homemade magnet and is observing the magnetism capacity that this magnet establishes with a nail, in a simple experiment, where she compares the magnetism capacity of the homemade magnet with the magnetism capacity of a bar magnet. With the description of this experiment, it is possible that we interpret the Leisha investigation as an investigation about the intensity of the forces between home and industrial electromagnets.

can you tell me what is it

richard nixon led the investigation that resulted in alger hiss being convicted of prejury.
