An electo-magnet is used in an electric bell.
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
An electromagnet is a temporary magnet that produces a magnetic field when an electric current passes through it, whereas a permanent magnet retains its magnetic properties without needing an external electric current. Electromagnets allow for control of the magnetic field by adjusting the current, while the strength of a permanent magnet is fixed.
A permanent magnet is necessary for an electric motor to function effectively because it creates a magnetic field that interacts with the electric current flowing through the motor's coils, causing the motor to generate rotational motion. This interaction between the magnetic field of the permanent magnet and the electric current is essential for the motor to convert electrical energy into mechanical energy efficiently.

An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.

Look to see if it's got a coil connected to an electric power source or not. If it does, it's an electromagnet, if not, it's a permanent magnet.

the soiled cannot be a permanent magnetic as it becomes a temporary magnet it jokes to the bell and hits it as that is done it brakes the current ad de magnetized causing it to fall back into position and that happens continuously that causes the ringing of the bell

An electromagnet is typically stronger than a permanent magnet because it can be adjusted by changing the electric current flowing through it. Permanent magnets have a fixed magnetic strength that cannot be easily altered.
