What is the primary function of a solenoid?
Generating a controlled magnetic field
What happens to the magnetic field outside a solenoid?
It is zero
What does adding an iron core to a solenoid do to the magnetic field?
Strengthens the magnetic field
How does the magnetic field inside a solenoid behave?
It is nearly uniform
What is the direction of flow of the magnetic field in a solenoid?
Parallel to the coil axis
What determines the magnetic field strength in a solenoid?
The number of turns and current through the solenoid

An array uses contiguous memory locations, while a linked list does not
Study Notes
A solenoid is a type of electromagnet that generates a controlled magnetic field through a coil wound into a tightly packed helix[1
