Solenoids are often used to operate the starter switch in a car engine. When a car is turned on, electric charges flow through the solenoid. The magnetic field that the solenoid generates causes a switch to move and close. The closed switch starts the engine. What does this tell you about the material of the switch?

Sagot :

The magnetic force allows to find the result for the question about the characteristics of the material is:

  • The material must be metallic.
  • Iron is the metal that has the most electrons with unpaired spin and feels the greatest magnetic force.

Ampere's Law.

Ampere's law explains the formation of the magnetic field due to the movement of the charges in the solenoid wire.

magnetic force characteristics.

For the switch to move it must be a metal that is attracted by the magnetic field, to increase the force to the maximum possible it must be a metal that has many electrons with unpaired spin and these can feel the force of the magnetic field.

One of the most used metals is iron, which has 5 unpaired electrons and is the one that most feels the forces of the magnetic field.

In conclusion using the magnetic force we can find the result for the question is:

  • The material must be metallic.
  • The Iron is the metal that has the most electrons with unpaired spin and feels the greatest magnetic force.
