The diagrams showing forces between current carrying wires gave a good idea of how something resembling a magnetic force could arise from a velocity-dependant electric force.
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge: The implications of this expression include: 1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
Magnetic Forces on Moving Charges. The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule.
If Bx = 0, calculate the magnetic field B. Convert the relevant quantities to SI units. Write the components of the force exerted by an external magnetic field on a particle with velocity components vx, vy, and vz.
Force = charge x velocity of the charge x magnetic field strength.
The magnetic force existing on a moving charge is in the direction at right angles to the velocity and also the direction of the magnetic field vicinity.
Online physics calculator to calculate force of magnetic field using current, length and angle between current and magnetic field.
Magnetic Forces Cannot Perform Work on Moving Charges. Force is always perpendicular to velocity, therefore the magnetic force on a moving charge is never applied in the direction of the displacement, therefore a magnetic force can do no work on a moving charge...
You can calculate the magnitude of the magnetic force without using the right-hand rule, so long as you know the angle, , between the velocity vector and the magnetic field vector: The sin term is important...
A particle with charge -5 nC is moving in a uniform magnetic field B = -(1.2 T)k. The magnetic force on the particle is measured to be F = -(3.6*10^(-7) N)i + (7.6*10^-7)j. Calculate the x and y components of the particle's velocity.
