Ampere's Law, Cylinders, Solenoid & Toroid
The magnetic induction produced inside an ideal solenoid, depends on which of the following quantities?
(a) number of turns per unit length.
(b) radius of the wire.
(c) current flowing throught it.
(d) permeability of the medium.
Show answer and solution
Answer: (d)
- For an ideal solenoid .
- It depends on turns per unit length , current and permeability .
- It does not depend on the radius of the wire.
- So the answer is (d): (a), (c) and (d).
