You're in a physics lab, armed with a glass rod sporting a positively charged 50-pC label (because even rods deserve proper attire, right?). Now, imagine you're feeling particularly sprightly and decide to give that rod a toss with a horizontal velocity of 10 m/s due west. But here's the kicker: the Earth's magnetic field decides to join in on the fun, sweeping in from the north like an overeager party guest. With the magnetic field at 5x10^-5 T pointing due north parallel to the ground, let's calculate just how much force this magnetic mischief will exert on our airborne rod. It's like the Earth's way of saying, "Hey, I see you throwing stuff around, let me give you a gentle nudge!"
