The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
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.
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.
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.
No, an electric bell typically contains an electromagnet rather than a permanent magnet. When current flows through the coil of wire in the bell, it generates a magnetic field that attracts an iron striker, causing the bell to ring.

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 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.
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.
An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, while a refrigerator magnet is a permanent magnet that can hold items to a refrigerator or other magnetic surface without needing an electric current. Electromagnets can be turned on and off by controlling the electric current, while refrigerator magnets retain their magnetism without the need for an external power source.
A permanent magnet is made of material that naturally produces a magnetic field, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
The magnet super-amplifies the EMF field, and possibly has amperage running through the poles.
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.
