A solenoid is a coil of wire wrapped around a metal core. When an electric current is passed through the wire, it creates a magnetic field that can attract or repel magnetic objects.
A toroid is a coil of wire wrapped around a donut-shaped iron core. The iron core is made of a magnetic material, so it can attract magnetic objects. When an electric current is passed through the wire, it creates a magnetic field that can attract the iron core and the objects inside the coil.
The key difference between a solenoid and a toroid is the shape of the core. This shape determines how the magnetic field is created and how the objects are attracted or repelled
