many stores have bar magnets pick a random one and go to it, Micheals is a good choice, yoyu can buy cloth there as well.
You can find that at the mall at any other furniture care stores. And if you have luck you might find them at your nearest Wal-Mart store
A magnets pull is strongest at the poles.
circular because you can find small circular magnets called "rare earth super magnets" at the store called princess auto
You now have 2 bar magnets, each with half the magnetic force of the original.
Bar magnets are already magnetized. They don't need to add wire and electricity.
One key difference between a bar magnet and a horseshoe magnet is their shape. Bar magnets are long and rectangular, while horseshoe magnets are U-shaped. Another difference is their magnetic field strength, with horseshoe magnets typically having a stronger magnetic field at the poles compared to bar magnets.
No, electromagnets are stronger than bar magnets.
long magnets (in the shape of a bar) with a north and south angel
Yes, because electromagnets can lose their magnetism.
only one... but there are difrent shapes...
They need not be. Many electromagnets are circular disks or toroidal (donut shaped). Bar magnets, not surprisingly, are bar shaped - often with a rectangular cross section.
Bar magnets are not typically used in speakers because they are relatively large and heavy compared to other types of magnets, making them less practical for the size constraints of speaker designs. Additionally, bar magnets can lose their magnetism over time due to demagnetization, which could affect the performance of the speaker. Instead, smaller and more powerful magnets, such as neodymium magnets, are commonly used in speakers.
