What's the name of the Coyote/Roadrunner cartoon?

My favorite sound is in a Coyote/Roadrunner cartoon. The Coyote had placed ball bearings on the ground, then covered them with birdseed. He then roller skates out of sight, & straps a magnet to his chest.

The Roadrunner zips up, & eats the birdseed, not knowing he was also eating ball bearings.

When he runs off, the Coyote, whose magnet is now being attracted by the ball bearings, is rolling towards the Roadrunner.

Every turn the Roadrunner made, the Coyote followed. One turn leads them to railroad tracks. They run/roll on the tracks for a while, then START to go over a bridge. The Roadrunner runs off the bridge, but the Coyote isn't able to follow, since NOW the magnet is attracted to an on-coming train! He TRIES? {Or runs for a BIT?} to get away from the train, but it overtakes him, & SOMEHOW, the Coyote ends up under the tracks with the magnet sticking STRAIGHT up! {And a piece of paper floats by the magnet}


COULD SOMEONE PLEASE find the title of this cartoon, so I can look for it on YouTube?




















Eight divided by one-half equals four squared!
