distance is the only insulator
A magnetic field is created around the wire when electric current flows through it. This magnetic field is known as the magnetic field of the current-carrying wire.
A magnet is not a conductor or an insulator. It is a material that can exhibit magnetic properties and create a magnetic field. The ability of a material to conduct electricity or resist the flow of electrons is unrelated to its magnetic properties.
Selenium is diamagnetic; it only creates a magnetic field in opposition to an external magnetic field.
A superconductor is the only material that completely repels magnetic fields, acting as an insulator from magnetism. This phenomenon is known as the Meissner effect, where a superconductor expels magnetic fields from its interior when it transitions to a superconducting state.
Selenium is diamagnetic; it only creates a magnetic field in opposition to an external magnetic field.
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
Mercury fits this description, as it has craters, cliffs (known as scarps), and a weak magnetic field. Mercury's magnetic field is only about 1% as strong as Earth's magnetic field.
harddisks are constructed from an aluminum platter (conductor) coated with a magnetic metal oxide (insulator)floppy discs are constructed from a plastic sheet (insulator) coated with a magnetic metal oxide (insulator)however the function of computer disks in no way depends on the property of being a conductor/insulator, only on its ability to retain tiny magnetic domains while permitting them to be easily modified.
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
Yes, any electrical conductor can serve as an electromagnetic insulator.
A Magnetic Force
An atom that is only weakly affected by a magnetic field is called diamagnetic. Diamagnetic atoms have all their electron spins paired, leading to weak repulsion when placed in a magnetic field.
