Magneto Bowling

Über

Do you like online bowling games? Have you ever tried a magnetized one? You might normally think of magnets attracting each other, but a wire carrying a current can also create a magnetic field. And an electrically charged particle, like an electron or proton, will move along those field lines. In this "bowling alley" game, you can position current carrying wires to produce a magnetic field pattern that can be used to guide your bowling ball (a proton) to knock down the pins without leaving the lane. No "gutter balls" please.
