The smallest unit of a substance that can exist alone and retain the character of that substance.

The basic component of all matter the smallest particle of an element that can exist either alone or in combination.

It can be harnessed from the Earth's natural heat associated with active volcanoes or geologically young inactive volcanoes still giving off heat at depth.

It can be heated, burned, fermented, or treated chemically to release energy.

It provided by the sun is the most inexhaustible and cleanest source of energy known. Its heat and light arrive week in and week out - free.

A Scottish physicist and one of the great theoreticians of all times, mathematically unified the electric and magnetic forces. He also proposed that light was electromagnetic radiation.and South poles.

He discovered an electric current flowing through a wire can cause a compass needle to deflect, showing that magnetism and electricity were related.

Magnetism is derived from the iron oxide minerals called ______________.

The term __________ is derived from ὑστέρησις, an ancient Greek word meaning "deficiency" or "lagging behind".

It can be considered to flow outward from the North Pole of a magnet.

The north and south poles of a magnet are the points of concentration of magnetic strength.

 These include aluminum, platinum, manganese, and chromium. The permeability is slightly more than 1. ___________ materials have a small, positive susceptibility to magnetic fields.

 These include bismuth, antimony, and copper, Zinc, mercury, gold, silver. The permeability is less than 1. ____________materials create an induced magnetic field in a direction opposite to an externally applied magnetic field, and are repelled by the applied magnetic field.  

If the wire is wrapped in the form of a coil, the current and its magnetic field become concentrated in a smaller space, resulting in a stronger field. With length much greater than its width, the coil is called ___________.

It refers specifically to the magnetic properties of iron.

It is a field in electronics that utilizes tiny, or micro, components to manufacture electronics.

The materials that permit the free motion of electrons.

The materials that have very few free electrons poor conductors.

The materials that have some characteristics of both conductors and insulators.
