Magnetic force Definition, Formula, Examples, & Facts

WebUnlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750. If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value. Web1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B. 2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees … Web12 sep. 2024 · Lenz's Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz’s law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere. takeoff dead tmz
