The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite directions have a repulsive force ...
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among ...
Feb 15, 2023 · Figure 11.8.2: Direction of Magnetic Field Around a Current Carrying Wire. Thus, there is yet another very convenient right-hand-rule for the direction of magnetic field around current carrying wires. It is demonstrated in the figure above. You need to point the thumb of your right hand in the direction of current.
A magnet is any object that can attract other materials with magnetic properties through a magnetic force. Every magnet has a north pole and a south pole. Either pole will attract iron. The direction of magnetic force between two magnets depends on how the poles are oriented. Opposite poles attract.
Feb 2, 2023 · The magnetic field at a distance r from an infinitely long wire carrying current I1 is given by. B1 = μo I1 / 2 π r. When a second wire carrying current I2 is brought closer and kept parallel to the first, it experiences a force given by. F = I2 L B1. Or, F = μo I1 I2 L / 2 π r. The force per unit length is.
