Show Me The Physics
Force on a moving charge in a magnetic field is maximum when ... a) .... the charge is Fast or Slow?
Fast
b) Big Charge or Small Charge?
Big
c) ... magnetic field strong or Weak?
Strong
1. Fmag = Bqv
B - flux density of magnetic field (strength) q - charge (C)
v - velocity (m/s)
Magnetic force is maximum
Magnetic force = 0
... parallel to field
2. Direction of magnetic F on a charge moving through a magnetic field

2) Thumb - direction of moving
charge
3) 4 fingers - direction of
magnetic Field
4) Palm - direction of force on charge
