Difference between Solenoid and Toroid
Difference between Solenoid and Toroid are in tabular form below –
Solenoid and Toroid both works on the principal of electromagnetism. Actually we can call them electromagnet when we pass current through them. The magnetic field due to solenoid and toroid is same. The solenoid has immeasurable length and the magnetic field due to the current carrying solenoid can be easily shown by the examining the field due to circular current. There are various types of solenoid like Linear solenoid, Rotary solenoid, etc. Solenoid has many very useful applications like locking system for doors, it has some major role in the medical devices, etc.
Solenoid | Toroid |
1) A solenoid is formed by the wire wound closely in the form of cylinder and the wires are electrically insulated.
2) The magnetic field in solenoid is uniform everywhere and it is zero outside it. 3) The magnetic field is created outside the solenoid. 4) Magnetic field due to solenoid is (B)= 5) The magnetic produced by the solenoid can be given by: F = μ0 nl |
1) A toroid is simply formed by the bending of solenoid in a circular shape.
2) The magnetic field will have equal magnitude at all the points of the circle also the field is tangential everywhere to the circle. 3) The magnetic field is created within the toroid. 4) Magnetic field inside and outside : (B)=0 5) The magnetic field due to toroid can be given by: B = μO NI/2πr |
