Here is another thing from the same website just not shortened:
Similarities between magnetic fields and electric fields:
- Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges).
- Like poles repel; unlike poles attract
- Electric field points in the direction of the force experienced by a positive charge. Magnetic field points in the direction of the force experienced by a north pole.
Differences between magnetic fields and electric fields:
- Positive and negative charges can exist separately. North and south poles always come together. Single magnetic poles, known as magnetic monopoles, have been proposed theoretically, but a magnetic monopole has never been observed.
- Electric field lines have definite starting and ending points. Magnetic field lines are continuous loops. Outside a magnet the field is directed from the north pole to the south pole. Inside a magnet the field runs from south to north.
Answer:
They Come in Two Opposite Varieties
Explanation:
Charges come in positive (+) and negative (-) varieties. The fundamental positive charge carrier is the proton and the negative charge carrier is the electron. Both have a charge of magnitude e = 1.602 × 10-19 Coulombs.
Opposites attract, and likes repel; two positive charges placed near each other will repel, or experience a force which pushes them apart. The same is true of two negative charges. A positive and a negative charge, however, will attract each other.
Electricity and Magnetism Are Two Sides of the Same Phenomenon
