Question

What is the difference between solenoid and toroid? ​

Answer 1

Explanation:

1. A solenoid is cylindrical in shape whereas toroid is circular.

2. Magnetic field is produced outside in solenoid whereas magnetic filed outside of toroid is zero and the magnetic field is produced within.

3. The solenoid has a uniform magnetic field whereas toroid does not have a uniform magnetic field within.

Answer 2

Toroid is form when you have wound conductor around circular body. In this case you have magnatic field inside the core but you dont have any poles because circular body dont have ends. This can be used where you want minimum flux leakage and dont need magnatic poles. i.e. toroidal inductor, toroidal transformer.

Solenoid is forn when you wound conductor around body with limb. In this case magnatic field creates two poles N and S. Solenoids have little bit flux leakage. This used where you want magnatic poles and flux leakage is not an issue. i.e. relay, motors, electromagnates
