A regular magnet achieves its magnetic field due to the alignment of its component atoms. An electromagnet induces a magnetic field through an electric current that travels around a conductive core.

∙ 14y agoregualar magnetic is to do with mass and gravity i think whereas electro magnetic fields require a current to induce an electrical field producing an electromagnet where the charge can be regulated by current

What do magnets attract that electromagnets do not?
Nothing, elctro magnets act just the same as permanent magnets
How do electromagnets affect nearby magnets?
If an electromagnet is close enough, it will either attract or repel other magnets.
What three ways are magnets and electromagnets alike?
they are both a type of magnet
Why is an electromagnet better that a bar magnet?
Electromagnets can have higher "domain currents" than permanent magnets, and have no non-aligned nor anti-aligned domains like permanent magnets tend to have (or get over time).
Do all magnets have the same power?
No, some are more powerful than others, as there are your normal refrigerator magnets that hold a few sheets of paper and there are super electromagnets that can hold cars.
How are magnets alike and How are magnets different?
My answer id they have different shapes and colors.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Why do cranes use electromagnets instead of permanent magnets?
Electromagnets are stronger and weigh far less than permanent magnets.
What do magnets attract that electromagnets do not?
Nothing, elctro magnets act just the same as permanent magnets
Are electromagnetic magnets permanent?
No, electromagnets are not permanent.
A permanent magnet can affect?
A permanent magnet can affect magnets and electromagnets.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What is one advantage of using electromagnets instead of permanent magnets?
Electromagnets can be turned off and off
What types of magnets are used in a MRI machine?
Electromagnets
What are three types of magnets?
They are permanent, temporary and electromagnets
Can electromagnets be stronger then permanent magnets?
Yes (and often are).
Are Magnets and electromagnets are used in many devices?
yes
