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.

    How does a hall probe work?

    A:

    A Hall probe is a sophisticated instrument used to measure magnetic field strength. It is a thin film that measures the transverse voltage when it is placed in the magnetic field. The Hall probe works on the Hall effect that was discovered by the scientist E.H. Hall in 1879.

    Is titanium magnetic?

    A:

    Titanium is considered paramagnetic, as it has no standing magnetic field of its own, but it develops one in the presence of an externally applied magnetic field. According to the University of Maryland, titanium is able to induce an electrical current in some metals, but only weakly.
