kidia Posted March 21, 2006 Posted March 21, 2006 Please can anybody help me on this? The magnetic force on a moving electric point charge is given by F=qv*B where v is the velocity of the charge q and B the magnetic field. Derive the components of the magnetic force Fx, Fy, and Fz.
Klaynos Posted March 21, 2006 Posted March 21, 2006 well consider each of the 3 vectors in the equation to actualy be vectors then look at how the vector cross product works and take each componant individually.
Klaynos Posted March 21, 2006 Posted March 21, 2006 Do you know what a cross product of two vectors is? If you consider that v and B are both vectors, and then look at the result from the cross product you will have a single vector with 3 dimentions, this multiplied by q will be the F vector, you can then just split the vector into it's x,y.z componants for showing the 3 seperate componants...
swansont Posted March 21, 2006 Posted March 21, 2006 Please can anybody help me on this? The magnetic force on a moving electric point charge is given by F=qv*B where v is the velocity of the charge q and B the magnetic field. Derive the components of the magnetic force Fx' date=' Fy, and Fz.[/quote'] it's F = qv X B Where X signifies cross product. That it's a cross product is important. Have you covered cross products?
kidia Posted March 21, 2006 Author Posted March 21, 2006 Thanx,cross products I learned it in mathematics.
