What is the cause of magnetism?

Question

For my science homework my teacher asks. "what is the cause of an electrical charge and of magnetism?"

Answer 1

forget about the links...

i will answer your question right NOW.

1. moving electrical charges generate magnetic fields and vice versa. ( basic physics )

2. all atoms have moving electric charges ( electrons ).

3. in most substances, these charges are randomly oriented in space. however, in magnetic materials ( e.g. certain metals ), these charges can be aligned in the same direction to create a magnetic field that is measurable.

4. this alignment can occur naturally, or be induced by electrical currents around the substance ( e.g . electromagnets ).

5. essentially, when most of the atoms in a material are aligned in the same position ( i.e. all the electrons are spinning in the same direction ), magnetism is produced.

hope it answered your fab question.

In physics, magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials. Some well known materials that exhibit easily detectable magnetic properties are nickel, iron, some steels, and the mineral magnetite; however, all materials are influenced to greater or lesser degree by the presence of a magnetic field.
