A bar magnet's pull is strongest?
No, electromagnets are stronger than bar magnets.
Why would a bar magnet pick up more paper clips than an eletromagnet?
?? lol i dont know what electro magnets u have been using! if it is a homemade electro magnet, try increasing the coils in the wire ro the power u are putting into it. does the bar magnet (permanent magnet) have a larger surface area than the electro one? also, you do know that the magnetic potential of electro and permanent magnets vary right? they use electro magnets in junk yards that are capable of lifting scrap cars with eaaase
How are electro magnet like bar magnets?
a bar magnet and a electromagnet are alike in many ways. the are alike because both of them are magnets. but there are plenty other ways they are alike
Is a bar magnet stronger than a u-shaped magnet?
circular because you can find small circular magnets called "rare earth super magnets" at the store called princess auto
What is a magnadur?
Permanent bar magnets are those bar-shaped magnets with opposite poles at either end. Magnadur magnets are ceramic magnets with their poles on their flat faces.
Is a bar magnet stronger than a you shaped magnet?
Not necessarily.
Where is a a bar magnets strongest pull?
A magnets pull is strongest at the poles.
What happens when a bar magnets cut in half?
You now have 2 bar magnets, each with half the magnetic force of the original.
Are bar magnets stronger than horseshoe magnets?
There are some variables like what the magnet is made of and how it was initially magnetized. If a bar magnet is bent into a horseshoe shape to make a horseshoe magnet, the magnetic field will be more dense (stronger) across the gap of the horseshoe magnet than it would have been anywhere around the bar magnet from which it was made. And since magnets are strongest at their poles, horseshoe magnets can use both their poles at once while bar magnets can only use one pole at a time.
What are bar mangnets?
long magnets (in the shape of a bar) with a north and south angel
What magnets act like several combined bar magnets?
A "Neodymium magnet or Super Magnet".
What comes in varicties called bar horseshoe and electro?
compass
