Iron (Fe), nickel (Ni), cobalt (Co), dysprosium (Dy), gadolinium (Gd), ceramics as ferrites and others, alloys, some organic compounds, etc.
The strongest magnet known today is the alloy Nd2Fe14B.
A magnet
Iron, nickel, and cobalt are examples of substances that are attracted to magnetic force. These materials contain magnetic domains that align in the presence of a magnetic field, causing them to be attracted to magnets.
Paramagnetic substances are those that are weakly attracted to a magnetic field, such as oxygen and aluminum. Diamagnetic substances, on the other hand, are weakly repelled by a magnetic field, like copper and bismuth. The key difference between them lies in their response to magnetic fields: paramagnetic substances are attracted, while diamagnetic substances are repelled.
Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
Diamagnetic substances are materials that have no unpaired electrons and are weakly repelled by magnetic fields. When placed in a magnetic field, the orbital motion of electrons in diamagnetic substances generates small, opposing magnetic fields that cause a weak repulsion. Examples of diamagnetic substances include water, gold, and copper.
Magnetic substances are substances containing aligned dipoles. Dipoles are spinning electrons. In order for something to be magnetic, its dipoles must be aligned with each other, so that they face the same direction. The direction they face create a North end, while the opposite end creates a South end.Some substances, known as ferromagnetic substances, have permanently aligned dipoles. Other substances, such as paramagnetic and dimagnetic substances, require an external magnetic field to align, or 'induce' the dipoles of the substance.To conclude, magnetic substances contain dipoles which are permanently aligned, or can be aligned through the force of external magnetic fields.Diamagnetic Substances are those Substances there is no resultant field as the magnetic field produce by both the spin and orbital motions of the electrons might add up to zero.
Magnetic substances are those that are attracted to a magnet while non-magnetic substances are not attracted to a magnet.
In non-magnetic materials,the magnetic moments of individual atoms are randomly arranged giving net zero magnetic moment such that these materials are not affected when an external magnetiv field is applied

Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
Iron, Cobalt, Nickel First of all, iron (Fe) is a magnetic substance. And so is nickel (Ni), cobalt (Co), dysprosium (Dy), gadolinium (Gd), ceramics as ferrites and others, alloys, some organic compounds, etc.
