Can you explain please?

Activity: Magnetic Force Score: Name (print): Date Magnetic fields work like electric fields, only with a twist. Magnetic field lines indicate the direction and magnitude of the magnetic field (vector) at any given point. Magnetic force, unlike the Coulomb force, acts only on moving charged particles. Note e = 1.6022 x 10-19 C. Use this figure for each of three situations. For each, q= - 15 e v = 3.25 x 10 m/s B = 2.5 mT 0 = 25. a) First assume a velocity coming out of the page (NOT the vector shown), and find: angle between v and B direction of the force (show and label as Fa) magnitude of Fa = b) Using the velocity vector as shown, find angle between v and B direction of the force (show and label as Fb) magnitude of Fb = c) For a velocity pointing up the page ( ty direction), find angle between v and B direction of the force (show and label as Fc) magnitude of Fc =
