Question

Ryan is experimenting with core materials for an electromagnet. he slides different for materials to a quail of current caring wire. sort the court materials based on whether they will or will not increase the strength of Ryan's electromagnet.

Answer 1

We can say that electromagnet is coils of wire which behave like bar magnets with a distinct South and North poles when a current of electricity passes through the coil.
The bigger the strength of Ryan's electromagnet, the better the conductivity of the material.
The material is as follows,
1. Silver and it is the best conductor.
2. Iron.
3. Nickel
4. Steel.
5. Glass which is an insulator, and
6. wood which is an insulator, and we thoroughly know that insulators they don't conduct electricity.
