−Magnets
− attract magnetic materials,it sets itself in N-S direction when
− suspended freely. It has two poles, like poles repel and unlike
− poles attract, poles cannot be separated. Both poles are equal In
− strength.The strength of the magnet is more near the poles, we
− use magnets in many fields of life,power is rate of work done and
− as electricity does work, electric power is rate at which it
− does Work. Electricity energy consumed is the product of power
− and time

−Magnetism
− is due to charges in motion. Unlike charges, magnetic monopoles
− do ot exist.
−
−What
− does a field line represent– it is not a force; but rather the
− effect that a charged particle will experience. The magnetic
− force is expressed in field lines, the field lines never
− intersect.
−
−Electricity
− and magnetism are linked. When current flows through
− conductors,magnetic field lines are produced which shows relation
− between magnets and electric Current. Electric potential is the
− work done to move charge infinity to to that point, when there is
− difference in potential.
