A natural magnet is permanent - an electromagnet loses its power when it's switched off.

Higher energy content
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).
What advantages do natural fabric have over synthetic fabric?
natural fabric a sobs more water the synthetic fabric. natural fabric is natural plants. synthetic fabric is man made.
How do you demagnatise a magnet?
You can demagnetize a magnet by: -dropping it many times -heating it over a flame -hammering it many times

Biomaterials can be classified into two main groups: synthetic and natural biomaterials. The latter exhibit several advantages over the former, such as biocompatibility, inherent biodegradability,
What are two advantages of artificial magnet over a natural magnet?

What are two advantages of a electro magnet over natural magnet?
A permanent magnet is always on; there isn't any way to turn it off. An electromagnet can be controlled; you can turn it on or off, or change the amount of magnetism by varying the current passing through the coils.
What advantage does a electromagnet have over a bar magnet?
The electromagnet can be turned on and off depending on whether it's needed or not.
What is an advantage of using an electromagnet over a permanent magnet?
The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
How can someone make an electromagnet stronger?
You have to take it out on a nice date first. Second, you have to pleasure the magnet for exactly 42 minutes. Third, you rub tons of ranch dressing all over the magnet on each side and keep it on there for 3-4 hours. These are the steps to make your electromagnet stronger.
What are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
What is a simple reason to how motors work?
If you take two magnets, you will notice that one end attracts one end of the other magnet and repels the other end. The opposite happens if you flip the other magnet over. It is possible to make an electromagnet by winding wire around a piece of metal. If you attach the wire to a battery it will attract one end of the magnet. If you attach the wire to the other end of the battery, it will attract the other end of the magnet.Also, with electricity, you can use a switch to change which end of the battery will go through which end of the wire. When the magnet comes close to the electromagnet, the motor throws a switch and suddenly the electromagnet repels the magnet. Part of the switch can be attached to the magnet. So motors work because electromagnets can both attract and repel.

Is a electro magnet stronger than a normal magnet?
it depends on how strong the electromagnet is. you basically choose how powerful to make an electromagnet when your designing one. one used for picking up cars at a junk yard is gonna be more powerful than one used in a kitchen appliance. and "normal magnet's" is not a good term for all other types of magnets. there are lots of different types of materials that can be magnetized, all of them are stronger or weaker then the others, all of them can also be made to different strengths, and all of them lose strength over time. the usefulness of an electromagnet is that they can be turned on and off depending on whether or not they have electricity running through them. http://en.wikipedia.org/wiki/Magnet
