Magnetism is the power to attract. It refers to the attraction to iron and other metals in electric currents and magnets, or to the other kind of attraction — where people want to be close to each other.

Different kinds of magnetism cause some magnets to attract, while others repel. Magnetism can also be called a magnetic force or magnetic attraction. Chemistry and earth science are two classes you might learn about magnetism in. Outside of the classroom, magnetism can be the force of attraction between people — if you have animal magnetism, don’t worry, a giraffe isn’t going to stick to you, but watch out for people with lovey eyes.

    magnetism produced by an electric current

    magnetic field creates parallel but opposing spins; varies with temperature

    phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a magnet

    phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed

    materials like aluminum or platinum become magnetized in a magnetic field but it disappears when the field is removed

    a phenomenon in ferrites where there can be incomplete cancellation of antiferromagnetic arranged spins giving a net magnetic moment
