Question

2) What is solenoid? List the material need for core.

​

Answer 1

Answer:

pls mark me brainliest

Explanation:

A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.

The material used to make solenoid iron core is not pure iron, it is ferriferous oxide. The iron core of solenoid is used to enhance the magnetism of the solenoid, therefore, you just need to choose the materials with magnetic permeability larger than 1, for example, the metal oxides like manganese, cobalt, etc.

Answer 2

Explanation:

the material used to make solenoid iron core is not pure iron it is ferrous oxide the irin core of solenoid is used to enhance the magnetism of solenoid , therefore you just need to choose the material with magnetic permeability larger than 1 for example the metal ixide like manganese , Cobalt
