What is the advantage of toroid over solenoid?
Advantages of toroidal winding. Because the toroid is a closed-loop core it will have a higher magnetic field and thus higher inductance and Q factor than an inductor of the same mass with a straight core (solenoid coils). This is because most of the magnetic field is contained within the core.
People also ask are solenoids ac or dc?
Solenoids that rely on electrical current fall into two main categories--solenoids that rely on AC (alternating current) as the source of power and solenoids that rely on DC (direct current) as the power source. Which is stronger solenoid or electromagnet? NOTE: A solenoid still produces a magnetic field but not as strong as an electromagnet of the same size. In fact, the magnetic field with the iron core is more than 1,000 times stronger (yes ? one thousand times).
Thereof, why does toroid have no poles?
At each head, there's also a tail, so no point is more N-like or S-like. Therefore a toroidal magnet has no poles. There's still a magnetic field inside, but it falls off more quickly outside than does the field from a magnet with poles. In respect to this, why is the magnetic field outside a toroid zero? After applying Ampere's Law, we see that the magnetic field at any point outside the toroid is zero because the net electric current is zero.
