Example and explanation of electromagnetism?

physics

Answer 1

Electromagnetism is a magnet made using electricity.

The following picture shows electromagnetism:

The wire is coiled on the nail and electricity is passed from the wire. the electricity forms an electric field and becomes a magnet but it is not permanent because if we stop the electricity flow, then it will no longer be a magnet.

This shows the magnetic field:

Answer 2

Electromagnetism involves the interaction between electric currents and magnetic fields. An example is an electromagnet, created by winding a wire around a core and passing an electric current through it. The magnetic field produced can attract or repel objects. This phenomenon is described by Maxwell's equations, unifying electricity and magnetism.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
