Question

two characteristics of magnetic force and gravitational force.

Answer 1

Answer:

Magnetic force: The magnetic field at any given point is specified by both a direction and magnitude. Magnetic lines of force start from the North Pole and end at the South Pole outside magnet. Two magnetic lines of force cannot intersect each other and they are continuous along the axis of the electromagnetic conductor.

Gravitational force:It obeys the inverse square law. It is always attractive in nature.  It is a long range force.The gravitation is the field particle of gravitational force.  It is the weakest force operating in nature.
