For many technical applications, it is desirable to have a uniform magnetic field, i.e. a field with the same strength and direction at every point in a certain region of space. As you discovered in the last checkpoint, this can be achieved with a solenoid, which is constructed by "stacking" many loops of wire, each with the same current. The superposition of the magnetic fields of the single loops creates a strong, nearly uniform field inside the solenoid, whereas the...
