Homework Statement


A current is passed through two solenoids placed in close proximity to each other as shown in the figure attached. Reproduce the figure showing the polarity of the two solenoids and the magnetic field pattern for the arrangement shown.


Homework Equations


There isn't really an equation to calculate the answer.


The Attempt at a Solution


I always try and attempt questions but literally if I tried to attempt this I would be guessing!

Look up the solenoid right-hand-rule. Are the currents in the two solenoids traveling in the same or different directions?
