In this lesson, we will learn how to calculate the strength of the magnetic field in a substance given its magnetic susceptibility.
A solenoid with an iron core is
long and is wrapped with 100 turns of wire.
When the current through the solenoid is
the magnetic field inside it is
What is the magnetic susceptibility of the iron core?
Suppose you wish to produce a 1.2 tesla magnetic field in a toroid with an iron core for which
. The toroid has a mean radius of 25 cm and is wound with 300 turns. What current is required?
There is a current of 1.5 A through the windings of a large, thin toroid with 200 turns per meter. If the toroid is filled with iron for which magnetic susceptibility
, what is the magnetic field within it?
