Magnetic Field

Sharona puts two magnetic toy vehicles very close to each other. What will happen next, and why?

• The toy vehicles will not move because the magnets are not touching.

• The toy vehicles will move closer to each other because the magnetic force will pull the vehicles together.

• The toy vehicles will move away from each other because the magnets are not touching.

• The toy vehicles will move away from each other because the magnetic force will push the toy vehicles apart.
