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.

    How does its magnetic field protect the Earth?

    A:

    Earth's magnetic field acts as a shield that diverts charged particles from the solar wind away from tropical and temperate latitudes thus preventing the loss of atmosphere due to impacting particles from the sun. Planets without strong magnetic fields tend to lose their atmospheres to space.

  • Q:

    How do magnets work?

    A:

    A magnet is an object or material that can produce a magnetic field of its own. That magnetic field is responsible for the property of magnets to attract or repel other magnets, and pull objects that are ferromagnetic, like iron. Electrons are the reason behind the production of magnetic fields and magnetism. In permanent magnets, spinning of electrons creates the magnetism.

    What is magnetic reversal?

    A:

    "Magnetic reversal" is the term used when the Earth's magnetic field reverses its polarity. This means that the poles flip so that the North pole becomes the South pole and vice versa. This flip takes thousands of years to complete based on computer models.

  • Q:

    If we move a conductor through a magnetic field, what will we create?

    A:

    Moving a conductor through a magnetic field creates an induced voltage. The voltage that is generated in the conductor is called the induced electromotive force (EMF). The induced EMF is higher if the movement of the conductor, within the magnetic flux, is faster; this is called Faraday’s Law.
