The iron filings in the image become induced magnets when they are near the bar magnet. Like all induced magnets: they are only attracted by other magnets, they are not repelled they lose most or ...

Others are also exploring induced proximity as a means of achieving tissue-selective target inhibition. Magnet’s ‘TrueGlues’ can for example achieve this effect, says Safina. One such ...

Ferroelectric materials are characterized by their ability to reverse their polarized positive and negative charges under an external electric field, akin to how the poles of a magnet can switch.
