Magnetic Force Definition Formula Examples Facts Britannica 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. Magnetic pole. magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. this motion can take many forms. it can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. magnetism is also associated with elementary.
Magnetic Force Definition Formula Examples Facts Britannica Magnetic dipole, generally a tiny magnet of microscopic to subatomic dimensions, equivalent to a flow of electric charge around a loop. electrons circulating around atomic nuclei, electrons spinning on their axes, and rotating positively charged atomic nuclei all are magnetic dipoles. the sum of these effects may cancel so that a given type of. Magnetic force equation. suppose a charge q is moving with a velocity v in a magnetic field of strength b, the formula for the magnetic force is. →f =q→v x →b f → = q v → x b →. here, f is represented as a vector, and v x b is the cross product of v and b. in terms of its magnitude, suppose θ is the angle between v and b, then. Introduction. a magnet is a rock or a piece of metal that can pull certain types of metal toward itself. the force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. magnetism works over a distance. this means that a magnet does not have to be touching an object to pull it. Magnetic force is the attractive or repulsive force exerted between magnets or magnetic materials. for example, when a magnet is brought close to a collection of iron balls, the magnetic force causes the balls to be attracted towards the magnet. this phenomenon demonstrates the ability of magnetic forces to influence and manipulate magnetic.

Magnetic force is a consequence of electromagnetic force and is caused due to the motion of charges. we have learned that a moving charge surrounds itself with a magnetic field. with this context, the magnetic force can be described as a force that arises due to interacting magnetic fields. learn more about magnetic force in detail. The magnetic energy is determined by calculating the magnetic energy density. it is denoted by the symbol ρm and is given by the following formula. ρm = 1 2bh= 1 2μoh2 = 1 2 b2 μo ρ m = 1 2 b h = 1 2 μ o h 2 = 1 2 b 2 μ o. the total energy, e, is the integral of ρm over a given volume. e =∫ ρmdv e = ∫ ρ m d v.
