The Meissner effect is related to an electrical current. The energy comes from getting the current started. Any energy in a magnetic field adds to the effort of getting the current started: this is basically the same as the energy in an inductance.
Superconductors float due to the Meissner effect, which causes them to repel magnetic fields, allowing them to levitate above a magnet.
yes Place the magnet near an iron ball and watch the ball accelerate toward the magnet.
A magnet contains magnetic energy, which is a type of potential energy that results from the alignment of the magnetic dipoles within the material of the magnet. This energy is capable of exerting forces on other magnetic materials without direct contact.
a magnet cannot keep you from falling under normal circumstances... however something called the meissner effect can cause the levitation of magnets in the presence of a superconductor. (which would have to be kept many hundreds of degrees below zero) the effect is only about an inch off the ground, though.
A superconductor floating works by using the Meissner effect, which causes the superconductor to repel magnetic fields. This creates a magnetic field that locks the superconductor in place above a magnet, allowing it to float without any friction or resistance.
A magnet does not have perpetual energy.
A superconductor.
In reality no. Though the size of a magnet does seem to affect the size of a magnetic field, it is in effect a ratio of volume, and does not change the effect of the magnetic field. The potential magnetism is not affected by size so much as composition of the magnet.
Yes, the lead magnet is effective in attracting potential customers to the website.
It depends on the gauss value of the magnet. Yourstood on a big magnet. It'scalled Earth. Youre a long way from the poles but it still has an effect on metals.
Magnetic energy.
Some other names include NdFeB, Neo, or Nib. This is also known as a rare-earth magnet and they have the potential to store large amounts of magnetic energy. Several different websites sell these - one is Applied Magnets.
