Question

Experimentally, the magnetic flux ?B in a solenoid was measured for various currents I. The data was recorded in the table below, and plotted in the graph on the right. The best fit line through the data is also drawn.

By definition, the inductance of some circuit element (e.g., a solenoid) is defined as the ratio of the magnetic flux ?B that passes through it to the current I in the element.

Experimentally, the magnetic flux B in a solenoid was measured for various currents L The data was recorded in the table below, and plotted in the graph on the right. The best fit line through the data is also drawn. What is the inductance of the solenoid?

Explanation / Answer

There isn't enough information to find the inductance. For example the cross-sectional area of the solenoid is needed (or a diameter or radius).
