Problem 50E
A toroidal solenoid has an inner radius of 12.0 cm and an outer radius of 15.0 cm. It carries a current of 1.50 A. How many equally spaced turns must it have so that it will produce a magnetic field of 3.75 mT at points within the coils 14.0 cm from its center?
ANSWER:
Solution 50E
Introduction
We have to calculate the number of turns the toroidal solenoid has.
Step 1
Since the point where we have to calculate the magnetic field is inside the toroidal solenoid, the magnetic field is given by
