Question

Ques. a. How is a toroid different from a solenoid?

b. Use Ampere's circuital law to obtain the magnetic field inside a torroid.

c. Show that:
i. Inside the torroid
ii. Outside the torroid at any point in the open space is zero.

Answer 1

Answer:

a.in what respect is a toroid different from a solenoid ? ... Solenoid is a straight coil having uniform number of turns per unit length. A Toroid is an endless Solenoid.It is in the form of Hollow sphere, having large number of turns.

Explanation:

b.Using Ampere's circuital law calculate the magnetic field inside the toroid. When a solenoid is in the form of a ring then it is treated as toroid. Toroid is basically, a hollow circular ring on which a large number of turns of wire are closely wound. Consider a toroid carrying current I and has N turns.

c. 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.
