Here it is...(adsbygoogle = window.adsbygoogle || []).push({});

The diagram shows a current balance loop that includes the conductor where l1 and l2 represent the segments of its length.

You have been asked to do an experiment that anazlyzes the relationship between magnetic field strength and current in a solenoid by plotting a graph. To make the necessary calculations for the graph you have been given the following possible headings for a data table:

Length 1

Length 2

Length of the solenoid

Current of the solenoid

Current in the current balance

Number of coil windings in the solenoid

Mass required to balance the current balance.

From the listing select the variables required to construct the data table.

I'm very confused with this question, I think the ones I would choose would be Length 1, Length 2, Current in the balance, and current of the solenoid.

Can you tell me if thats right, and if not help me understand the right answer?

Cheers
