For a magnetic force to exist, the charge q must be moving with a velocity v and under a magnetic field B that is not of the same direction of its velocity. The magnetic force of a moving charge is part of the Lorentz Force Law which is given by the formula:...
Direction:The direction of the magnetic force \((F)\) is perpendicular to the plane formed by \(v\) and \(B\), and it can be easily determined by the right-hand rule. According to the right-hand rule, to find the direction of the magnetic force on a positive moving charge, the t...
Is magnetism a push or pull force? When does the magnetic force equal the centripetal force? Does applied force cause acceleration? Are positive and negative charges affected by the magnetic force differently? A proton moving at 4.1 x 10^6 m/s experiences a magnetic field of 3.8 T. Calculat...
Gravity is a fundamental force in the universe. It acts on all matter at all times. A gravitational force will exist between any two objects that possess mass, regardless of the distance between them. This force gives us weight on Earth and keeps planets in orbit. Albert Einstein's theory ...
what happens if we put a wire carrying current into a magnetic field? ! it contains moving charges, so we'd guess it feels a force we can work out a formula for the force: force on each charge in time 螖, a charge = 螖flows in in time 螖, a charge moves so the total charge ...
The torque on the loop is related to the magnetic moment of the loop μ and the magnetic field vector B by the equation (4.40)τ=μ×B. To estimate the magnitude of the magnetic moment of the atom, we shall consider the hydrogen atom as a classical charge distribution. We imagine that...

The force between two magnetic poles is similar to the force that exists between two charges. In both cases, the force can be one of attraction or repulsion. In the 1780s, Charles-Augustin de Coulomb, a French physicist, developed the mathematical formula for calculating the force for either...
