Electromagnets

The word "electromagnet" is composed of two words, ‘electro’ and ‘magnet’. It is a type of magnet in which an electric current helps in the generation of a magnetic field. Electromagnets usually consist of two major parts, wire and a coil around which the wire is wound. This is called a solenoid. When an electric current is allowed to pass through the coiled wire, the electric current produces a magnetic field. This magnetic field is present only when current is passing through the wire.

Question

Given a solenoid that has N1 turns, a length L1 and a radius rį where a current running through is

second is not connected to a source. Give the expression of:
a) The initial magnetic field the first solenoid creates inside its coil
b) The initial magnetic flux through each loop of the second solenoid

Suppose you wish to produce a 1-T magnetic field in a toroid with an iron core for which magnetic susceptibility is x = 3 x 10³. The toroid has a mean radius of 14 cm and is wound with 600 turns. Hint a. What current is required to produce this magnetic field in the iron core? Current of b. For comparison, what current is required to produce the same magnetic field in an air-filled toroid of same geometry? Current of A is needed. Submit Question A is needed for toroid with no iron core. While it is not always practical to have region of magnetic field filled with ferromagnetic materials, this dramatic increase in strength of magnetic field produced is useful in some applications you will see in upcoming chapters.
