Q:

What is magnetic force?

A:

Quick Answer

The technical definition of magnetic force is the mechanical force exerted from a magnetic field to a magnetic pole that is placed within that particular magnetic field. Magnetic force involves the simultaneous attraction and repulsion that occurs between particles that are electrically charged and are within the magnetic field itself.

Full Answer

A prime example of a magnetic field is the manner in which iron reacts when placed in proximity to a magnet. Magnetic force is the primary reason why electric engines are able to function; these engines contain rotating coils of wire that are driven by magnetic force exerted by a magnetic field on an electric current.

  • Q:

    What causes attraction and repulsion in magnets?

    A:

    The magnetic field lines of a magnet run from north to south, according to HowStuffWorks. The force leaves the north pole and enters the south pole of another magnet, which creates a closed loop. Magnets attract each other when their lines of force are running in the same direction, and they repel each other when their lines of force travel in opposite directions.

  • Q:

    How do I demagnetize something?

    A:

    A magnet can be demagnetized with heat, hammering or an electric current. A metal behaves as a magnet when all its units or domains are aligned in one direction. When this alignment is destroyed and made random, the magnetism is also destroyed.

  • Q:

    What metals are attracted to magnets?

    A:

    Metals that are attracted to magnets include iron, nickel and cobalt. The majority of metals are not attracted to magnets, including copper, silver, gold, magnesium, platinum and aluminum. However, the metals that are not attracted to magnets may magnetize slightly when placed in a magnetic field.

  • Q:

    What are the properties of magnets?

    A:

    Magnets have five properties. Their force of attraction is greater at the poles than in the middle. Similar poles repel. Opposite poles attract. The south pole of a bar magnet suspended by a thread moves toward the north pole. Magnets attract objects made of iron, cobalt and nickel.
