The magnetism of an electromagnet is natural (it comes out of the laws of physics), but the magnetism disappears when the electricity is turned off - it is not a permanent magnetism.

What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?

Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.


Is magnet natural or man made?

Magnets exist in nature as natural minerals such as magnetite. However, magnets can also be man-made through processes like magnetization of materials or creating electromagnets.


How are electromagnets different from magnets?

You can turn electromagnets on and off.


Are electromagnetic magnets permanent?

No, electromagnets are not permanent.


A permanent magnet can affect?

A permanent magnet can affect magnets and electromagnets.


What advantage do electromagnets have over other magnets?

Electromagnets can be turned on and off by controlling the flow of electricity, while permanent magnets have a fixed magnetic field. This makes electromagnets more versatile and suitable for a wider range of applications. Additionally, electromagnets can produce a stronger magnetic field than most permanent magnets.


What are the differences between electromagnets and permanent magnets, and how do they function differently?

Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.

Can electromagnets be stronger then permanent magnets?

Yes (and often are).


Are Magnets and electromagnets are used in many devices?

yes


How are electromagnets different from regular magnets?

Electromagnets are different from regular magnets because they require an electric current to create a magnetic field, whereas regular magnets have a permanent magnetic field without the need for electricity.
