What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
What step is critical to ensure that you do not lose important data during installation?

What are the advantages of memory chips?
They make sure you dont lose your work and they help you to store more data
What causes an outboard motor to lose power after running for 1 hour or so?
No gas?
When you double your distance from a speaker you lose how many db?
Sound pressure is inverse square law for distance, so doubling distance from a speaker cuts the power by 4. Since the db scale is 3 times log2 (power ratio), a reduction of power by 4 represents -6db.
Would magnets attract to a paperclip under water?
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
Do magnets lose their power?
No.If you break the magnet, it is still a useful magnet.
Why does rust change a magnet's power of attraction?
The oxidation causes magnets to lose protons that are essential for magnetic attraction
Will magnets lose it's power by rubbing?
You can destroy the magnetism of a magnet by hammering ,heating or using a alternating current method.
What types of magnets are easy to magnetized but lose magnetism quickly?
temporary magnets
What types of magnets are easy to magnetize lose magnetism quickly?
temporary magnets
What types of magnets are easy to magnetize but lose magnetism quickly?
temporary magnets
Can magnets lose magnetism?
Yes.
What happens to magnets when they are heated?
it will lose its magnetism OR it will get weaker
Why do car batteries lose charge?
Dead cell in the battery or something is on pulling power from the battery. Light or relay.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Why does diesel engine lose RPMs going uphill?
Any engine will lose RPM going up a hill, its called gravity and the engine has to overcome it. The heavier the vehicle the more RPM you lose. Thats also why transmissions have all the extra gears. Lower gear equals more pulling power and less speed, higher gear is less pulling power and more speed.
