The Solenoid and the Toroid

सोलनॉइड और टोरोइड

In this Class 12 Physics topic from Moving Charges and Magnetism, students learn how a current-carrying solenoid produces a nearly uniform magnetic field inside its turns and a weaker field outside. They study how the field depends on current, number of turns, and the medium, and use Ampere’s circuital law to understand the result. The topic also explains the magnetic field of a toroid, its circular arrangement of turns, and the confinement of the field within its core.
