Scientists have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method ...

The development of an ultrathin magnet that operates at room temperature could lead to new applications in computing and electronics — such as high-density, compact spintronic memory devices — and new ...

If you break a compass needle in two, the resulting smaller magnets will have both north and south poles. Keep cutting the needle and each individual part will always have two poles - even down to the ...
