Is Refrigerator magnet Electromagnet

Answer 1

The magnets that stick to the front of a refrigerator are permanent magnets, not electromagnets. There is also a permanent magnet embedded in the door seal of most domestic fridges to keep the door shut.

add All magnetic fields are caused by the movement of electrons. In a permanent magnet, several of the electrons have their spin axes aligned, thus creating the magnetic field. [From the math, conceptually there could be a magnet monopole, but no one has found one yet.]

In an electromagnet, the current of the electrons along the wires creates the external magnetic field.

The way a permanent magnet (eg frig magnet) works is that the magnet induces a magnetic field of opposite sign in the sheet steel of the frig body, and the permanent magnet and the induced field attract each other.

Answer 2

all elictrecal stuff has to be conected to the earth through the earth line if not it will cause irretic feeling when touch due to accumelated static charge

Answer 3

Simple most refridgerators are made up of iron or contain iron in their frame and, iron being magnetic, causes magnets to stick
