Magnetic
when an object attracts or repels a magnet
Magnetic refers to an object or substance that produces a magnetic field. A magnetic field is a force field that surrounds a magnetic substance, like a magnet or certain metals. The magnetism of a material is caused by the movement of electrons within the atoms, which create a north and south magnetic pole within the material. Like poles repel each other, while opposite poles attract each other.
Magnetic materials are important in many fields ranging from simple fridge magnets to complex technologies like MRI imaging, electric motors, and generators. Magnetic fields are also used in many industrial applications to sort metal objects or in electronic devices like hard disk drives, speakers, and transformers.
The strength of a magnetic field can be measured using units like Tesla or Gauss. Magnetic fields can be classified as permanent or temporary. Permanent magnets, as the name suggests, maintain their magnetic field indefinitely, while temporary magnets lose their magnetism once the magnetic field is removed. Additionally, there are also electromagnets which use an electric current to create a temporary magnetic field within a wire coil.
