"Magnetises" Natural Recordings by Native Speakers
The verb "magnetises" is the third person singular present tense of the verb "magnetise", which means to cause something to behave like a magnet, or to induce a magnetic field in a material. For example: "The strong magnetic field magnetises the metal, making it attract other objects."
A magnetar is a type of neutron star that is capable of producing extremely powerful magnetic fields and explosive events, known as magnetar flares. It is a dense, spinning ball of neutron-degenerate matter that is formed from the remains of a massive star that has undergone a supernova explosion. Magnetars are characterized by their incredibly strong magnetic fields, which are trillions of times stronger than the Earth's magnetic field. This strength leads to a number of unique properties, including the ability to produce powerful magnetic flares that can release enormous amounts of energy in a short period of time.
