List of Properties of Magnet:

Electromagnetic survey methods are based on two fundamental principles: Faraday’s law of electromagnetic induction and the fact that electric currents generate magnetic fields, expressed in Ampère’s law.

Magnets exhibit the following properties:

• All magnets have two poles: the North Pole and the South Pole.
• Magnets attract ferromagnetic materials such as iron, nickel, and cobalt.
• The magnetic force of a magnet is stronger at its poles than in the middle.
• A freely suspended magnet always points in North-South direction.

• Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
• Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
• Directive Property – A freely suspended magnet always points in a north-south direction.

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.

Magnetic materials that are difficult to demagnetize are used to construct permanent magnets. Permanent magnet applications are in loudspeakers, earphones, electric meters, and small motors. A loudspeaker consists of a wire carrying an alternating current.

It is denoted by M and its SI unit is Am2. When a magnetic material like iron is placed in a magnetic field, it gets a magnetic dipole moment. The magnetic dipole moment acquired per unit volume is known as Magnetization. Its SI unit will be Am2m = Am .

Whereas magnetization is measured typically in amperes/meter, the magnetic polarization is measured in teslas.

Coercivity is usually measured in oersted or ampere/meter units and is denoted HC.
