प्रश्न
Differentiate between a circular coil and a solenoid.
Advertisements
उत्तर
A circular coil is a single loop of wire creating a magnetic field perpendicular to its plane, while a solenoid consists of multiple coils wound closely in a cylindrical shape, producing a uniform magnetic field inside.
