Question

Traits of an Electromagnet ?​

Answer 1

$answer$

Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.An electromagnet works because an electric current produces a magnetic field.

Answer 2

Electromagnets are based on the physical phenomenon of physics called induction. The process of induction causes electrical fields to produce magnetic fields, and magnetic fields to produce electrical fields. This phenomenon was documented in 1831 by the physicist Michael Faraday. His experiments sought to prove that an appropriately designed apparatus could produce electricity from magnetic fields. His discovery that a rotating magnetic field within an electrical field led to the inverse property of induction: that introducing an electric field into a magnetic one would produce additional magnetic fields.

Traits are :

• Magnetic Power
• Power Strength
• Polarity
