What is the magnetic field inside a long, ideal solenoid?

Step 1: Understand what a solenoid is. A solenoid is a long coil of wire that creates a magnetic field when an electric current passes through it.
Step 2: Recognize that an 'ideal' solenoid is one that is long and tightly wound, meaning the ends do not affect the magnetic field inside.
Step 3: Know that the magnetic field inside the solenoid is created by the electric current flowing through the wire.
Step 4: Realize that the magnetic field lines inside the solenoid are straight and parallel to each other, indicating that the field is uniform.
Step 5: Conclude that the magnetic field inside a long, ideal solenoid is uniform and parallel.
