A metal rod is forced to move with constant velocity along two

parallel metal rails, connected with a strip of metal at one end. A magnetic field of
magnitude B = 0:350 T points out of the page.
a) If the rails are separated by L = 25.0 cm and the speed of the rod is 55 cm/s, what
is the absolute value of the induced emf?
Eα-N(∆ϕ/∆t)
b) If the rod has a resistance of 18Ω and the rails and connector have negligible
resistance, what is the current in the rod?
Umm im thinking I have to solve A first to get this one but idk how to solve A
c) What are the magnitude and direction of the magnetic force acting on the rod? F=ma? Again im lost
